System icons missing in kubuntu 21.04

[Paul Chaffey]

[Impact]

This affects Groovy → Hirsute upgrades for users who had qt5-default package installed.

For these users, apt could replace libqt5gui5 with libqt5gui5-gles, which is not suitable for most desktop systems and can result in all kinds of broken UI (such as missing icons).

[Test Plan]

1. Get a groovy amd64 system (e.g. a chroot).
2. Install qt5-default package.
3. Replace groovy with hirsute in /etc/apt/sources.list.
4. Run "apt update".
5. Run "apt dist-upgade".

Incorrect behavior:

The following packages will be REMOVED:
  libqt5gui5 qt5-default qtbase5-dev
The following NEW packages will be installed:
  ... libqt5gui5-gles ...

Correct behavior: only qt5-default is removed, libqt5gui5 is not removed and libqt5gui5-gles is not installed.

[Where problems could occur]

The fix is adding "Breaks: qt5-default" in three packages:
- qtbase5-dev (built from qtbase-opensource-src source).
- qtbase5-gles-dev (built from qtbase-opensource-src-gles source).
- libqt5gui5-gles (built from qtbase-opensource-src-gles source).

It can affect apt's dependency resolver. Example of a problem may be the resolver keeping the old behavior in some cases.

[Other Info]

See this post for details on what the -gles packages are:

[Original Description]

Hi, just testing Kubuntu 21.04 on a spare machine. The upgrade initially was fine, but I then install kdenlive and krita which has messed up the system icons and window decorations (corners of windows are showing black squares).

I have been through all the normal checks and even created a new user, but the bug still persists. The system Icons are broken in the system and nothing to do with the user account.

lsb_release -rd
Description: Ubuntu Hirsute Hippo (development branch)
Release: 21.04

Looking at the following may shed some light on the problem...

Thanks, Paul.

[Paul Chaffey (paul-chaffey)]

Some updates:

All kde apps when starting report on the command line (Eg. when starting kate):

Icon theme "Breeze" not found.

tried reinstalling breeze-icon-theme but its still the same. The package is there, but kde cannot find it after the upgrade to 21.04 from 20.10.

[Paul Chaffey (paul-chaffey)]

Just to show window decorations

[Paul Chaffey (paul-chaffey)]

I have sorted this out by using the following from another post:

sudo service sddm stop
sudo apt remove libqt5quick5-gles
sudo apt install libqt5quick5
sudo service sddm start

For me, when removing libqt5quick5-gles, libqt5quick5 was automatically install, so line 3 wasn't needed. Not sure why it was installed in the first place...

[Paul Chaffey (paul-chaffey)]

This bug report may not be filed in the right place - somewhere like Kubuntu - kde - qt

I would mark as solved also, but I don't see a button for this - perhaps someone at Ubuntu can do it...

[Daniel van Vugt (vanvugt)]

qtdeclarative-opensource-src appears to be the correct place, because it is the source package of libqt5quick5-gles

If you no longer need a fix though, then "Won't Fix" is the status to set.

[Dmitry Shachnev (mitya57)]

Hi! I am the Qt maintainer here.

The fix mentioned in https://bugs.launchpad.net/ubuntu/+source/qtdeclarative-opensource-src/+bug/1920130/comments/4 is the correct one. libqt5quick5-gles is not intended for general use, it should be only installed on OpenGL ES capable hardware.

However, I really want to understand how users end up with this package being installed. See this related thread in Debian: https://lists.debian.org/debian-devel/2021/01/msg00404.html.

If anyone else upgrading from Groovy to Hirsute sees this, please attach here these log files (or, if you think they are private, send them directly to me <email address hidden>):

- /var/log/apt/history.log
- /var/log/apt/term.log

Also if removing libqt5quick5-gles tries to remove any other package (which does not have -gles in name), please paste the list of those packages.

[poet_imp (paul-lemmons)]

I Experienced this problem and "sudo apt remove libqt5quick5-gles" followed by a reboot corrected the problem completely. Attached are the requested logs.

[Dmitry Shachnev (mitya57)]

@poet_imp Thanks for the logs! Unfortunately, these are only the latest logs and they don't explain what happened when you upgraded Ubuntu.

Maybe you can attach the historical logs from /var/log/apt too? They have names like history.log.*.gz and term.log.*.gz. If you upgraded recently, then I guess it would be *.1.gz. Otherwise you can look at modification dates.

[Owen Williams (ywwg)]

I think this is what you're looking for. I upgraded to 21.04 and had the same issue.

```

[Paul Chaffey (paul-chaffey)]

In case anyone missed this above:

I have sorted this out by using the following from another post:

sudo service sddm stop
sudo apt remove libqt5quick5-gles
sudo apt install libqt5quick5
sudo service sddm start

For me, when removing libqt5quick5-gles, libqt5quick5 was automatically
installed, so line 3 wasn't needed. Not sure why it was installed in the
first place...

[Dmitry Shachnev (mitya57)]

Hi Owen,

Thanks a lot for sharing the log. Indeed, qt5-default seems to be the cause of this bug. In https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976389#15 I explained in more detail my understanding of why this is happening.

The fix should land in Impish (development release) in a few hours, and then I will look at a fix for Hirsute (21.04).

[Dmitry Shachnev (mitya57)]

The fix has landed in Impish (21.10) today:

https://launchpad.net/ubuntu/+source/qtbase-opensource-src-gles/5.15.2+dfsg-4

[Dmitry Shachnev (mitya57)]

As it turns out, this also needs a change in qtbase-opensource-src. Change in -gles is not enough:

This bug was fixed in the package qtbase-opensource-src - 5.15.2+dfsg-6

  * Backport upstream patch to adjust QMimeDatabase behavior (LP: #1857824).
