[SOLVED] Latest upgrades killed Plasma?

pchristy · 05-18-2022, 04:50 AM

Just applied the latest upgrades to my Pi 400, and I can no longer start Plasma (or sddm). Xfce can still be started from the command line.

Trying to start Plasma from the command line produces the following error:

Code:

symbol lookup error: /usr/lib64/libKF5IconThemes.so.5: undefined symbol: _ZN12KColorSchemaSEOS_

Any ideas, anyone? Not sure what package this has come from!

First time an upgrade has failed in many goes, so not a bad record!

UPDATE: Found the package - its "kiconthemes". Re-installed it straight from the dl.slarm64 repository in case it was an issue with slackware.uk, but no change.

rebuilt, try to update kiconthemes-5.94.0-aarch64-1.txz

No, that didn't work! Looks like it could be one of those "reflecting" errors, where although the message comes from one thing, it is because it can't find something else? (I don't know if I've explained that very well!)

There's nothing in either dmesg or Xorg.0.log to help either. Just to avoid confusion, I deleted Xorg.0.log and tried to start Plasma. After it errored out, there was still no Xorg.0.log, so it looks as if it never got as far as starting X.

Xfce starts and runs perfectly!

Is there anywhere I should look for useful information?

I looked at the sources and the link in the current library and they match

Code:

nm -D /usr/lib64/libKF5IconThemes.so.5 |grep _ZN12KColorSchemeaSEOS_                                                                                                                                 
                 U _ZN12KColorSchemeaSEOS_

Code:

kiconthemes-5.94.0# grep KColorScheme -r
src/kiconcolors.h:     * KColorScheme(QPalette::Active, KColorScheme::Window);

_ZN12KColorSchemaSEOS_ there really is no such function, but also not in the library:

Code:

nm -D /usr/lib64/libKF5IconThemes.so.5 |grep _ZN12KColorSchemaSEOS_

Curioser and curioser!

I'm at a loss! Has anyone else reported an issue? Is there anything else I should check, log-wise?

Perhaps I should just re-install kde?

I would try and change icon themes, but I can't even run kde system settings from xfce! In fact, I can't run ANY kde programs from xfce, which implies its something pretty fundamental. Is it possible to change icon themes from the command line?

Might not be able to do much more tonight, and tomorrow is my wife's birthday, so time will be limited!

maybe really try upgradepkg --reinstall
and other kde programs with the same error ?

pchristy · 05-18-2022, 04:14 PM

OK, did "slackpkg reinstall kde", which re-installed the whole of kde. Didn't make any difference. However, this time I tried "startx" instead of "startplasma-x11" and got an Xorg.0.log file, which I attach.

Not sure it helps though!

yes, there are no errors X because they work fine. sddm if it does not start, you need to look at the log.

OK, but which log? As far as I can find, kde /sddm doesn't create one - not in /var/log anyway.

Won't have much keyboard time today (wife's birthday!)

UPDATE: OK, I found this in .local/share/sddm which looks promising (see attachment). I disabled sddm (set run level back to 3 in inittab) after it crashed at first and have been using "startx" or similar since. But it looks like the same issue is stopping both sddm and plasma.

Its not a user configuration issue. I created a new user as a test, but it crashed with the same error as before.

According to the changelog, the only kde packages that have been updated are:

kde/calligra-3.2.1-aarch64-19.txz: Rebuilt.
kde/krita-5.0.6-aarch64-5.txz: Rebuilt.
kde/plasma-workspace-5.24.5-aarch64-2.txz: Rebuilt.
kde/step-22.04.1-aarch64-2.txz: Rebuilt.

I've checked both slackware.uk and your own repository.

Plasma-workspace seems to be 5.24. Is this right?

In any event, the updates listed above have not changed anything.

this is a simple reassembly, I did not include in ChangeLog.

pchristy · 05-20-2022, 05:24 AM

OK, perhaps I need to do a complete reinstall of kde again, as slackpkg wouldn't have picked up any changes...

pchristy · 05-20-2022, 06:05 AM

OK, did a complete reinstall of kde from dl.slarm64.org - just in case slackware.uk hadn't updated.

No difference, still getting the same error. Am I the only one, or are you able to reproduce this?

Yes, I checked for the exact same problem.

after reinstalling all packages of version

Code:

pgradepkg --reinstall try *-5.94.0*

or

Code:

slackpkg reinstall 5.94.0

the problem is gone.
