Andre's questions

After upgrading to 24.04, neither the Outline Client nor Outline Manager appimages works any more.

I did install libfuset64 as recommended in other places, but I get SUID permission errors.

$ ./Outline-Client.AppImage 
[584847:1001/220953.594798:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_Outlintr1Gf9/chrome-sandbox is owned by root and has mode 4755.
[1]    584847 trace trap (core dumped)  ./Outline-Client.AppImage

If I run outline with ./Outline-Client.AppImage --no-sandbox then it works perfectly fine, but this is supposed to be much less secure.

I'm wondering if there is a way to run outline without having to use the --no-sandbox flag

I'm unable to launch some snap packages after my system crashed a couple hours ago. Everything was perfectly fine before my system crashed. Started happening when I managed to get my system working again.

Discord for example gives me this error:

ERROR: not connected to the gnome-3-28-1804 content interface.

The docker daemon also won't start:

Brave browser also didn't start, at first I thought I just need to re-install, which worked, BUT without saving my brave data, so the browser now doesn't know any of my pages, bookmarks, settings or anything. (I did NOT use --purge when removing). See: Snapcraft removed all my data without --purge for that issue

EDIT: The issue with brave data have been resolved, it did save that data, just didn't auto-restore the data when I reinstalled. (See the link above for details).

Some information:

~ » snap version                                                                                              64 ↵ andre@andre-office
snap    2.49.2
snapd   2.49.2
series  16
ubuntu  20.04
kernel  5.4.0-72-generic

I was told that I can re-install an app safely using snap remove brave and then snap install brave without losing the app data, so long as you don't add --purge.

So this is what I did. During the remove step there was a message: "backing up data for #112". I then re-installed, ran the app. Yeah, all data is gone, complete blank slate...

My question is: Is there ANY other location where the data might have been backed-up to other than /snap/<app>/ where I can restore it from?

EDIT: Just discovered that the data was saved:

~ » snap saved                                                                                                     andre@andre-office

I ran sudo apt-get remove --purge mysql* and didn't notice that it also had ubuntu-desktop ubuntu-desktop-minimal gnome-control-center ... and a whole bunch more.

I've not rebooted yet, but I'm worried my system will go belly up once I do.

1. What will happen on reboot?
2. Why on earth would it remove those packages when it doesn't start with mysql

I want to install ubuntu core on a IoT2020 device (by Siemens) [1].

I couldn't find any Ubuntu Core images or Gadget Snaps for this device, but after a quick web search it seems I can create my own image using ubuntu-device-flash.

I'm not sure what options I should be choosing for the IoT2020 device though. I'm hoping someone can point me in the right direction?

Related: Is there a place I can request or recommend adding this device to their list of pre-built images?

EDIT: If a existing Ubuntu Core image and gadget snap will work with this device, that would be even better. I just don't know which.

EDIT: I've now also posted a question on Siemens support forums regarding this [2], as well as a github issue on their meta-iot2000 repo [3]

I installed gimp via snap install previously and even though window decorations were missing, I was still able to use it. Today however, I opened up gimp and it's completely unusable (fonts is missing it seems).

See the screenshot attached.

I'm unable to add new rules to my firewall using ufw gui. In the Log I get the following error.

[19/01/16 14:16:43] Error running: /usr/sbin/ufw allow in from any to any port 8000 > WARN: Duplicate profile 'Apache', using last found | WARN: Duplicate profile 'Apache Secure', using last found | WARN: Duplicate profile 'Apache Full', using last found

Can anyone explain how I can fix this? It was working fine before I upgraded to 15.10.

EDIT: Re-opened since the errors came back. and previous solutions didn't work.

I've been happy with 13.04 since launch. This week however something odd started happening. Sometimes after login, the desktop will show, without the global menu or dock. Cannot open dash etc. Sometimes, after rebooting it would just work again, and I can continue my work.

Suddenly today, this got far worse. Now my pc will show the dock and global menu, but I cannot access the desktop (invisible icons, right-click does not work), and the background looks completely borked (see screenshot below). The mouse when over certain windows is constantly flickering.

I've attempted to completely re-install ubuntu 13.04, but even this didn't solve the problem. I have my /home on a separate partition, so I have all my current settings saved, could it be something there?

I still cannot work for long period, because the entire desktop will at random crash, and I lose all window decorations, etc.

I have a deadline for Friday, and my system is in-operable. Does anyone know how I can debug/fix this issue?

EDIT: Installing proprietary drivers does not fix the problem. In fact it results in a blank screen on boot.

EDIT: Extra info, I can boot into my windows 8 partition and play games without any display issues.

EDIT: lspci -nn output

EDIT: Today I downgraded to 12.10, using the same extended partition for my home folder. Same problems. However, if I log into a guest session, then none of these issues exist. everything works the way it normally does. Is there an issue with my home folder?

EDIT: It's starting again. Something is definitely wrong with unity in 13.04. It keeps changing my monitor settings. I boot up and see the following As soon as I go into the monitor settings to change the monitor settings, the UI breaks like in previous examples, and the only way to fix it is to remove the compiz-1 folder and monitors.xml folder, but after reboot I still see the two desktops overlayed like in the image.

Bus error (core dumped)

A friend of mine owns a house with 10 rooms which he's renting out to students. He provides them with Internet access.

Unfortunately, regardless of hes appeals and warnings to the students, they keep downloading illegal files via torrents. He already received 2 warning letters that he's going to be charged.

He now has a extra PC and wants all traffic to the Internet to go through this computer. At the same time he'd like to shape the traffic, and also have the ability to see who the offending students are.

Neither he or I are any good with ubuntu/linux server stuff, but we don't mind reading. Can anyone point us to what tools we would need to install in ubuntu (preferably GUI tools) to assist in this matter?

Any links to websites containing such info could also be handy, since I couldn't find anything myself. (probably cause I'm not using correct search terms)

Thanks,

Andre

Just installed natty. When running the Live session the wireless was working perfectly. After installation however, it doesn't work at all. There is an option to install the Broadcom Restricted drivers, but when I click activate, I just get a "jockey" error, pointing me to /var/log/jockey.log.

This is what that file contains:

This is the only issue I'm having with Natty, I'm hoping someone can help me fix this (if it's not a bug).
