Broken KDE environment when updating libplist

Issues & Assistance Unsupported Software (AUR & Other)
1

When logging in to the KDE wayland desktop session, it had a crappy default theme saying the normal theme was broken, and logging in made the screen flash black for a second and kick me back to the login screen.

Luckily I have GNOME installed also, so I logged into that. Then launching Konsole produced the following error:

konsole: error while loading shared libraries: libplist-2.0.so.3: cannot open shared object file: No such file or directory

I checked and have libplist installed, but it updated recently and the files it has on my system are:

$ exa | rg libplist
lrwxrwxrwx     23 root  5 May 05:00  libplist++-2.0.so -> libplist++-2.0.so.4.3.0*
lrwxrwxrwx     23 root  5 May 05:00  libplist++-2.0.so.4 -> libplist++-2.0.so.4.3.0*
.rwxr-xr-x    68k root  5 May 05:00  libplist++-2.0.so.4.3.0*
lrwxrwxrwx     21 root  5 May 05:00  libplist-2.0.so -> libplist-2.0.so.4.3.0*
lrwxrwxrwx     21 root  5 May 05:00  libplist-2.0.so.4 -> libplist-2.0.so.4.3.0*
.rwxr-xr-x   100k root  5 May 05:00  libplist-2.0.so.4.3.0*

So I made a link:

sudo ln -s /usr/lib/libplist-2.0.so /usr/lib/libplist-2.0.so.3

and this actually fixes the problem and allows me to launch konsole (and probably log in to KDE as well).

Still, this is very weird to me. Why would the arch package libplist update this filename when other packages still depend on the old one (is this a general arch problem)? Why would KDE packages be built on specific versions of libplist when they are all symlinks to the stable filename libplist-2.0.so?

Looks like you need to reboot.

Installing two desktop environments on the same system is a high risk configuration and common source of troubles.
If Gnome works but KDE doesn't the culprit is in something between the two, not on konsole, which seems to me to have no relation with that library.
You should check which packages depend directly or indirectly on that library, but unfortunately you'll have to fix it by yourself...

The problem began after doing a reboot. I did update the system again after successfully getting to gnome, but that didn't fix it. Just did another reboot to check and, if I remove the manual symlink I made, the problem persists.

I suppose that makes sense. pactree -r libplist states that both gnome and KDE packages rely on it.

However, it isn't as though installing libplist without any gnome packages will make it contain the libplist-2.0.so.3 file (which does appear necessary for konsole). So I was more trying to understand how this could come to be an issue at all, and (assuming the reason I ran into this and no one else did is because I have 2 DEs) how it would successfully work on a system without Gnome.

Already did as detailed by the post. Should I have posted somewhere other than Issues and Assistance?

Glad you fixed it, no problem.
I'd just like to point out, to the broader readers/audience, that, in general, fixing a problem by symlinking is a risk, maybe a temporary workaround. Libraries receive soname bumps when they are not backwards compatible.
Don't worry about the category. Starting from issues & assistance is fine. We move it as needed. If it will become clear that the issue is KDE specific I'll move it back.

So I have only KDE but a similar experience after updating . . . except nothing will run and I can't reboot or log out after the update. If I force it to shut down then I get the same default screen with the same inability to log in and this message:

"The current theme cannot be loaded due to the errors below, please select another theme.

file:///usr/share/sddm/themes/NetLogin/Main.qml:9:1: plugin cannot be loaded for module "org.kde.plasma.core": Cannot load library /usr/lib/qt/qml/org/kde/plasma/core/
libcorebindingsplugin.so: (libplist-2.0.so.4: cannot open shared object file: No such file or directory)"

This could be a different problem (giving a quick look at the pactree for libplist yesterday I saw it's used indirectly by a lot of packages, going primarily into KDE, but also Gnome).

This theme seems to be quite old (not updated since more than 2 years).
I haven't been able to (quickly) find their github, but I assume something might need to be fixed there.
You should be able to boot to a tty and, from the command line, install/configure a different theme.
Also startx from the command line might work and give you a graphical session.
Additionally

This should be available, if your system is updated, provided by libplist:
https://archlinux.org/packages/extra/x86_64/libplist/
In my opinion it would be cleaner to open a new topic for this.
