An Ubuntu developer asked me to perform tests on some unofficial packages. Now my system is broken and I can't get support because I have unofficial packages installed. The package did not come from a PPA. How do I remove the developer's packages and revert to using only the official repos?
I'm looking for a canonical answer that works for any package or packages because this happens a lot.
Here is a screenshot of the Xfce appearence settings in 18.04 (left) compared to 16.04 (right):
As you can see, the same font, font size, hinting, and DPI is selected.
In the bottom right is an overlay of the two showing that the word "Style" renders approximately 1 pixel taller and wider on 18.04. Since it is only 10 pixels tall to begin with this represents a 10% increase in size.
In addition, some other fonts render smaller in 18.04 than they do in 16.04 (not pictured, but they do.)
Why does this happen?

And yes, unattended-upgrades are enabled in the configuration:
10periodic :
APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Download-Upgradeable-Packages "0"; APT::Periodic::AutocleanInterval "0";
20auto-upgrades :
APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Unattended-Upgrade "1";
So why is unattended-upgrades not installing any upgrades?
Requested extras:

All three of those entries are from me running "sudo unattended-upgrades --dry-run" manually.

Note that this computer gets rebooted every day. Previous log unattended-upgrades-dpkg.log.2.gz is quite long and actually shows stuff being installed. It ends with this:

There are lots of sans fonts in Ubuntu, for example "Liberation Sans", "FreeSans", "Deja Vu Sans", "Noto Sans". But who made the one that is just called "Sans" and which package is it from?
I installed a snap from the store using snap find and snap install. After installing it I noticed that it behaves suspiciously. How do I report this?
I have a motherboard with a Marvell SATA controller. This controller is only used to drive the eSATA ports. By default Ubuntu loads the pata_marvell module to drive these ports. However, PATA does not support hot-swapping, which is a big drawback for an eSATA port. The workaround for this is to put
options ahci enable_marvell=1
in /etc/modprobe.d/marvell-ahci.conf and then rebuild the initramdisks. This causes the ports to be controlled by ahci.
Why is pata_marvell the default? Why would I want to use it instead of AHCI? And are there any possible problems with using AHCI?
I am attempting to build a modified libdbusmenu package. It builds correctly if I build it locally:
sudo apt-get build-dep libdbusmenu
wget https://launchpad.net/~a-j-buxton/+archive/dbusmenu/+files/libdbusmenu_12.10.3%2B13.10.20130913-0ubuntu2.1.diff.gz
wget https://launchpad.net/~a-j-buxton/+archive/dbusmenu/+files/libdbusmenu_12.10.3%2B13.10.20130913-0ubuntu2.1.dsc
wget https://launchpad.net/~a-j-buxton/+archive/dbusmenu/+files/libdbusmenu_12.10.3%2B13.10.20130913.orig.tar.gz
dpkg-source -x libdbusmenu*.dsc
cd libdbusmenu*
dpkg-buildpackage
However, in a PPA, one of the tests fails to run which causes the build to fail. The actual test output is not written to the buildlog:
How can I solve this issue?
It might come down to more closely reproducing the build environment used by the PPA builders. If so, how do I do that?
I have tried building using a pbuilder chroot - this works correctly on my local system.
Lintian produces the following warnings on the package:
W: libdbusmenu source: quilt-build-dep-but-no-series-file
W: libdbusmenu source: patch-system-but-no-source-readme
W: libdbusmenu source: ancient-standards-version 3.9.2 (current is 3.9.4)
For the purpose of this question, "large directory" means for example a Linux kernel git repository, or the Chromium source.
If I rm -rf a large directory like this from the shell, it is deleted in only a couple of seconds at most.
If I move it to trash first and then empty the trash, the first operation takes under a second, then the actual delete takes several minutes (we are talking double figures.)
Why is emptying the trash so slow? What is it doing when it says "preparing." How much preparation does it actually take to run rm -rf ~/.local/share/Trash/?
Under /usr/share/gnome-session/sessions are files which describe the different types of sessions available from gnome-session. In these files is a list of required components, eg for shell:
RequiredComponents=gnome-shell;gnome-settings-daemon;
or for fallback:
RequiredComponents=gnome-panel;gnome-settings-daemon;
This appears to be a list of executables, but it is not. If I change gnome-panel to some other type of panel, the session does not start, and I see the following errors in ~/.xsession-errors:
gnome-session[2003]: WARNING: Unable to find required component 'xfce4-panel'
So my question: What is a component, how are they defined, and where does gnome-session look for them?
When helping someone we often ask them to show the output of a command eg:
sudo fdisk -l | pastebinit
If the user is not using an English locale, the output may be in a foreign language:
Disk /dev/sda: 750.2 GB, 750156374016 bytes
255 huvuden, 63 sektorer/spår, 91201 cylindrar, totalt 1465149168 sektor
This complicates support. How can one run a command with an override on the system locale to get English output?
For example, in Ubuntu we have:
but other indicators have only a single version that works on both:
still others have no gtk2 version and will NOT work with gtk2-based desktops:
Why do some indicators need to be maintained in two versions while others do not?
I have written a tool which automatically formats and copies files to USB flash drives when they are inserted. It needs the drive to be unmounted to format it.
Normally Nautilus will automatically mount the drive when inserted, so I have to wait for this to happen and then unmount the drive before formatting it. The only problem is that if the user has disabled automounting then my program will wait forever.
I could change the dconf auto-mount setting when my program starts, and then change it back when it exits, but this is not a good solution because the setting wil not be restored if my program crashes.
How can I temporarily prevent Nautilus from automounting USB drives only during the time when my program is running?
I have a LAMP webserver configured to serve multiple websites. Each virtual host has various PHP applications, mainly Wordpress.
When users sign up to the Wordpress sites, email is sent by PHP through to postfix, and then on to the receiver. The problem is that postfix is identifying itself to the remote server with the contents of /etc/hostname, which is not a fully qualified domain name. Some mail servers reject this and the mail bounces.
Additionally, the return path is being set to one of the vitual host domains, seemingly at random.
I could set /etc/hostname to one of the website domain names, but then the emails from the other websites would have a wrong server in the headers, and this would not fix the return-path issue.
Possibly related, apache2 says "could not determine the server's fully qualified domain name" on startup.
How do I fix this so that each website can send email without revealing the other websites hosted on the server?
Example error:
Oct 15 20:29:32 Ubuntu-1204-precise-64-minimal postfix/smtp[17214]: CD087E00DF6: to=<*****@*******.**>, relay=spool.mail.gandi.net[217.70.184.6]:25, delay=0.29, delays=0.12/0/0.09/0.07, dsn=5.5.2, status=bounced (host spool.mail.gandi.net[217.70.184.6] said: 504 5.5.2 <Ubuntu-1204-precise-64-minimal>: Helo command rejected: need fully-qualified hostname (in reply to RCPT TO command))
I have now set the FQDN in /etc/hosts and /etc/hostname, and restarted apache2 and postfix, and it still gives this same error. I don't even know where it is still getting the old hostname from as it is no longer stored anywhere on disk.
I have found a reproducable crash bug in xserver-xephyr. When I run the following command:
apport-bug /var/crash/_usr_bin_Xephyr.1000.crash
it sends a whoopsie report and does not ask me for any extra information such as how to reproduce the bug, which I know. It also doesn't file a real bug report. How am I supposed to do it?
I have a raw file but I don't know the pixel format or the width of the image. I need a tool that can quickly display the data and allow me to try different formats easily. An example of such a tool for Windows would be 7yuv. What software exists for this task on Linux?
Note: This has nothing to do with digital camera raws, which is frustrating my attempts to use Google to answer this question.
I have an XBox joypad:
Bus 005 Device 004: ID 045e:0289 Microsoft Corp. Xbox Controller S
When I start Bastion from the terminal the following is output:
Number of joysticks: 1
Number of buttons for joystick: 0 - 10
Number of axes for joystick: 0 - 6
Number of PovHats for joystick: 0 - 1
When I load up the game it displays a message "press any key" and at this point, if I press a button on the joypad it advances to the main menu. However, the up/down/left/right controls do not work and the button will not operate the menu. When I enter the control configuration, the joypad section is disabled and displays a message "joypad not detected." If I enter the control customization and try to reconfigure one of the controls, noises can be heard when pressing joypad buttons, but the input is otherwise ignored.
Further information which may or may not be relevant:
My controller is an original Xbox controller, not a 360 controller. XNA games on Windows apparently only work with Xbox360 controllers because they use xinput rather than direct input, see eg here.
My controller works (almost) properly with MonoGame trunk samples, but Bastion uses a modified MonoGame and crashes when run against trunk, so I can't add debugging to see where the problem is.
Bug can also be reproduced with a Xbox 360 wired controller.
When I run Amnesia: Dark Descent or Superbrothers: Sword & Sworcery, the games are stretched across both my monitors, like this:
Limbo crashes on start-up:
How can I solve these problems?
Which source packages contain the source code of the indicated applets?
If the answer is a catch all source package like "gnome-applets", what is name and location of the individual applets within the source package?
Note: I am using 12.04.
First of all I open the dash and click the musical note icon. Then I search for an album or song. Now I've found it I want to send a link to my friend on facebook/twitter/google+. How do I do that?
