Question

I think I should be able to install a newer version. What am I missing?

Issue

Release-notes of a package home-assistant-snap shows the latest ver is 2022.5 and yet on my Ubuntu Core on RPi3 the latest is 2021.12.3. 5 months lagging. Its snap page (snapcraft.io) also lists that the latest/stable is 2022.5.

$ snap refresh home-assistant-snap --channel=latest/edge
home-assistant-snap (edge) 2021.12.3 from Giaever.online (giaever-online) refreshed

After successfully passing the password on the logon window, desktop blacks out. I can tell the monitor is powered. It just shows black. Having tried rebooting multiple times, I saw often that the background image of the desktop appeared but only briefly then the display blacked out.

K/b input seems to be working as I can tell my cursor is moving (confirmed that cursor moved to an external computer via synergy).

Unlike many threads, I see my on both 14.04 and 16.04 the NIC configs are stored in /etc/NetworkManager/system-connections, which is still discussed on some threads but not many AFAI have seen. And I haven't found any tool-provided command. E.g. in this thread someone gives a hint to update the ip address defined in an existing NIC config file (using find, sed etc.), but that's still a hack and there's no guarantee it'll still work once anything on the network manager or else on operating system changes.

Question: is there anyway to create / update files under /etc/NetworkManager/system-connections from command line?

I'm on Ubuntu 14.04 but info on newer distros is also appreciated.

My DELL 27inch monitor should be capable of 2560x1440 resolution. I've confirmed with Ubuntu 12.04 NVIDIA with DVI connection. Now on 14.04 Intel® HD 4600 with HDMI, the maximum resolution I see is only 1920x1080.

$ xrandr
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 597mm x 336mm
   1920x1080      60.0*+   60.0     50.0     59.9     24.0     24.0  
   1920x1080i     60.1     50.0     60.0  
   1600x1200      60.0  

Among many similar issues on askubuntu.com, I saw this one gives a command set that seems kind of promising, but after xrandr --output HDMI1 --mode 2560x1440, the OS' display setting tool says the display got 2560x1440 (that's what I want) but the DELL monitor got blacked-off and stated:

Current input timing is not supported by the monitor display. Please change your input timing to 1920x1080@60Hz or any other monitor listed timing as per the monitor spec.

How can I get 2560x1440 on my external DELL monitor?

On Ubuntu in "Systems Setting" --> "Display", I only see 800x600 resolution option. As I change the size of the VM window, it just expands/shrink accordingly, maintaining the same ratio (800x600) that is way too narrow for me.

Already tried but no good:

• On VM's setting --> "Display", I tried checking both on/off with "Accelerate 3D Graphics" or "User full resolution for Retina display".
• Add pref.autoFitGuestToWindow = "FALSE" to ~/Library/Preferences/VMware Fusion/preferences (https://communities.vmware.com/message/2342718)

Any idea is appreciated.

• VMWare Fusion 6.0.3 with VMWare Tools installed.
• OSX 10.9.3 on Macbook Pro, Retina 15-inch
• VM: Ubuntu 12.04 64b

After I upgraded from Raring, I started not seeing bars of Unity and also on all windows. Some phenomenon:

• CTRL + ALT + T not opening terminal
• Happens only with my main user account
  • ie. When logging in with Guest account things look normal.
  • Log in display also looks normal.
• Wallpapers on bacgground are displayed.

Only possible way to operate on terminal is from ssh -X, but:

I was at a loss and upgraded to Trusty (that was original purpose anyway) but things remain the same. What's wrong? Thank you.

Since the last apt-get dist-upgrade this morning, I've started seeing nvidia-settings crashes when I try setting something with the error below:

$ The program 'nvidia-settings' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 666 error_code 2 request_code 139 minor_code 25)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Having spent a few hours already I've tried several things below and no luck:

• Rename ~/.nvidia-settings-rc --> New file was made at some point I'm not sure.
• Rename /etc/X11/xorg.conf --> New file hasn't been generated.
• Install bumblebee --> Had same situation with this ticket and gave up. Uninstalled.
• Tried installing and/or removing nvidia's libraries (versions tried: 304, 319, 331 afai remember)

Since it looks like the latest nvidia driver 331.20 was just released early this morning, I suspect the newly installed library contains a wrongdoer. But does anyone have an idea to fix this?

With either one of the following commands, I expect python-omniorb-omg to be installed, which didn't get so however. The package is a recommended package according to python-omniorb description in Raring.

$ sudo apt-get install --reinstall python-omniorb
$ sudo apt-get install --reinstall --install-recommends python-omniorb

I purged python-omniorb and ran the simplest command like below, then the recommended package got installed. Although

$ sudo apt-get install python-omniorb

Am I missing something wrong here with --reinstall option?

(I'm not sure how python-omniorb got previously installed while one of its recommended packages wasn't installed).

2 weeks after I bought t440s with Windows 8 bundled, I'm freaked out with it and want to replace with Precise. Using USB boot to make sure if it's run although the device looks like already certified by Canonical, Ubuntu can't find wireless device. I've found a workaround for a similar issue, I still don't know what to do.

The same URL from above says:

Network
    Intel Corporation Lynx Point-LP PCI Express Root Port 6
    Ericsson Business Mobile Networks BV Unknown

Also,

$ lsmod|grep intel
:
snd_hda_intel
kvm_intel
aesni_intel
ghash_clmuni_intel, aesni_intel
intel_ips

I'm not an expert at all with devices...I'd appreciate solution. Thanks!

Update) I'm required to use Ubuntu 12.04.

Update-2) I upgraded to 13.04, hopelessly expecting that doing so would just resolve the issue. Ended up seeing no improvement. I found the model of wireless module is Intel Wireless-N 7260 from this page.

Since I've found similar threads (1, 2) but are not helpful to my issues, I'm opening up a new question.

Occassionally when I run apt-get, I get:

The following packages were automatically installed and are no longer required:
:
  (list of packages)

This occurs often with the packages that I heavily use. However, because they are not used by the OS, the error message itself makes sense if required means OS is the one used to require those packages.

How can I stop this to happen / let OS know that I need these packages?

Since there ARE cases when this notification is actually useful (eg. packages that OS used to require are no longer in need AND I do not used them too), I prefer solution/workaround that allows case-by-case setting.

apt 0.8.16~exp12ubuntu10.11

I prefer on terminal using ALT-b to move to previous word/space (I'm not sure if this is normal behavior of terminal but at least on Gnome I can do that). But on unity pressing ALT only shows the menu tabs that are hidden normally. How can I disable that?

I'm on Quantal.

On my Ubuntu machine, a network printer on LAN is recognized (by just selecting Network on Add a New Printer menu). Applications recognize it too. However the info shown on the printer panel ("System settings" --> "Printer") does not seem what Ubuntu obtains from the printer; it's IP address is localhost, clicking "Jobs"-->"Show" always shows empty job list, and clicking "Print Test Page" doesn't do anything.

Probably because of that, I get an error when I try to print a pdf from Acrobat Reader.

lpr: unsupported document-format application/vnd.adobe-reader-postscript

Ubuntu Quantal, acroread v9.5.5, Canon MG6330

With the same file, I can print without any problem from Mac OSX 10.8.4. Is there any workaround? And if let me know also if any information is needed. Thank you!

Update 6/14/2013) Thanks for the comments and answer. I managed to be able to print from Ubuntu. With @quidage's answer, I was able to "operate" printer; Print Test Page sends "something" to the printer so that it beeps but without printing anything, and the admin web page on Ubuntu says the job is completed. Then I'm ashamed to say that I had to install driver...from this web site to select the printer I have.

Using gtk-recordmydesktop, I took this video that doesn't have any issue at its beginning (here I'm only focusing on a few seconds from the point both links start at). gtk-recordmydesktop yields .ogv and I converted it into mp4 command like:

HandBrakeCLI -f mp4 -i ./original.ogv -o ./converted.mp4

However, in another video that incorporates the video above as a result of editing, there starts to appear a glitch, which looks like a window at the back ground on the desktop of the computer at that time.

Question-1. Is there a way to avoid this kind of glitch happens with the video file that's already recorded?

Question-2. If the answer in Q-1 is no, are there things to avoid this to happen when I'm recording video snapshot? Since I've found gtk-recordmydesktop works the best for me I prefer to sticking to it, but I also welcome other tools if any for this purpose.

This thread seems to be discussing similar issue but no solution/workaround is reached.

Using Ubuntu Quantal, handbrake-cli 0.9.8ppa1~precise1, gtk-recordmydesktop 0.3.8-4.1ubuntu1

From here I obtained the latest deb file, double-click that opens Software Center and click install. I got:

The package is of bad quality
The installation of a package which violates the quality standards isn't allowed. This could cause serious problems on your computer. Please contact the person or organisation who provided this package file and include the details beneath.

Detail providd is posted here. On the same popped up window there's an option to "ignore and install" which I very much hesitate to go on with.

Also with the same .deb file I tried from commandline as suggested here:

sudo dpkg -i AdbeRdr9.4.6-1_i386linux_enu.deb

which yields:

Any idea to work around? Thank you.

I want to listen to streaming audio from Ubuntu using headset (Bose Bluetooth Headset Series 2). Although Bluetooth connection is established, I haven't been able to hear anything via the headset. How can I work this around in general (I know this might sound brutal but I don't have much knowledge in audio setting on linux) ?

When I use my other Bluetooth headset BlueAnt Q2 (http://www.myblueant.com/products/headsets/q2/index.php) streaming is going. In "Hardware" tab on sound setting panel (not sure how it's officially called but see the image below) shows my headset.

However, Bose one never appears on the same window while it's connected via Bluetooth, except for a few seconds after I manually disconnect the headset (this moment is snapshotted as the image below. When it's connected the Bose BT2 thing is never shown. Btw, with Android phone this headset works just fine).

Bose' manual indicates that

Make sure the device supports A2DP audio streaming.

So I tried to figure out if A2DP is enabled on my Ubuntu (referring to Can I use my computer as an A2DP receiver / bluetooth speaker?), finding that it's probably available as the result below shows:

My Serval laptop (vendor's, System76's, website no longer has info) has suddenly started immediate turn-off power recently. It's happened at least twice in last 2 days. Any idea is appreciated and please tell me which log files you need to investigate so that I'm happy to provide those.

I can only describe the situation non-numerically b/c I didn't record anything when it occurred but:

• CPU usage is high due to the app I started (roughly, the usage of all 4 cores is more than 75%, less than 100% on Gnome System Monitor)
• Application program running was a simulator for robotics (called Gazebo), which after a few minutes of running the phenomenon occurs. I've used the same tool before on this machine so shouldn't be the matter.
• Noise of the fan was the one of the busiest
• Memory usage was about 50%

Not sure if it's related but after I've upgraded to Precise, the fan has been making more noise even when the CPU usage is very low.

Environment: Ubuntu 12.04 (originally 11.04 upon purchase, then 11.10), Kernel 3.2.0-30-generic, Core i7 2GHz x 8, 11.7GB RAM, GeForce GTX 560M

Thanks.

Kernel Module Update was required when opening VMWare client (vmplayer) then following error occurs. Any idea would be appreciated.

Unable to start services.
See log file /tmp/vmware-root/setup-NNN.log for details    (Note: NNN looks like random numbers)

On GUI that show progress of updating, "Virtual Netowork Device" show red flag appears. Content of .log file is here: http://pastebin.com/wEKT5UHf

This page suggests installing linux-headers-generic and build-essential, which are already installed on mine (thus no good).

This could be 1st execution of vmplayer on my machine since I upgraded to Ubuntu 12.04 from 11.10.

Environment: VMware Player 4.0.3 build-703057

Although I've started to see this phenomenon after I upgraded my notebook from Oneiric to Precise, I'm not sure what is influencing. (1st one of the following image) I dragged the window on right to the bottom. Then while I move around cursor, (2nd image) the window moves back to the top rim.

In this example the one on left remains at the bottom for some reason. And this can happen to other application window (e.g. Firefox, System Monitor etc.) Any idea??

(Environment) NVIDIA Driver version: 295.40, Gnome Classic (when using Ubuntu as a desktop style, this issue didn't occur)

Can anyone tell me how to enable Emacs keybind on Chrome?

I found some links but they are either not clearly mentioning how to do so or not what I want (I don't want external tools to be run for this purpose).

My Ubuntu machine is connected to internet via wifi, and also connected to LAN by ethernet cable. Every time I log on, I have to run these 2 commands in order to set the proper gateway (wlan0 in my case) so that I can access internet.

% sudo route del default
% sudo route add default gw 192.168.3.1

To automate, I've tried several things that I've found on internet but didn't work so far. Though can't remember all of them, one of them is this:

(In /etc/network/interfaces, add the followings and reboot)
up route del default 
up route add -net 192.168.3.0/24 gw 192.168.3.1 dev wlan0

The result of route command right after boot (before running the operation shown above, 10.0.* is LAN) shows that eth0 is still set default gw against my desire:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.0.193.0      *               255.255.255.0   U     1      0        0 eth0
192.168.3.0    *               255.255.255.0   U     2      0        0 wlan0
link-local      *               255.255.0.0     U     1000   0        0 eth0
default         10.0.193.1    0.0.0.0         UG    0      0        0 eth0

I use Ubuntu 11.04

Has anyone got a direct solution?

Update 10/22/11) Since I might have changed many configurations, I don't know only these changes are the ones that take effect, but here are my solution. Now the computer allows both internet (wlan0) and local (eth0) on boot.

• (as the chosen answer indicates) Check both "Ignore automatically obtained routes" & "use this connection only for resources on its network"

• Modify /etc/network/interfaces as follows:

  auto lo iface lo inet loopback up route del default up route add -net 192.168.1.0/24 gw 192.168.1.1 dev wlan0
