TL;DR: Both pamac CLI and the pamac-manager GUI are unreliable for system upgrades. They are prone to crashing in the middle of an update, leaving the user with no feedback that the upgrade is continuing in the background.

Having previously tried to do a system update using the GUI, followed by the GUI crashing and the update continuing in the background, this time I tried the commandline:

$ pamac upgrade

809.4 MB/1.4 GB About 43 seconds remaining[1]    1202062 terminated  pamac upgrade

Then I tried again:

$ pamac upgrade
pamac: error while loading shared libraries: libalpm.so.15: cannot open shared object file: No such file or directory

I’m going to assume pamac is just a broken tool for system upgrades.

Minutes later, I tried pacman:

$ sudo pacman -Syu
:: Synchronising package databases...
 core is up to date
 extra is up to date
 multilib is up to date
:: Starting full system upgrade...
 there is nothing to do

Hmm… Did the upgrade happen in the background? What has just happened? Let me try pamac again:

$ pamac upgrade
Synchronizing package databases...
Refreshing AUR...
Nothing to do.
…
(plus a few extra AUR updates)

So, yeah, yet again pamac crashed, and the updated continued in the background with NO user feedback whatsoever.

Welp, then the only thing I can think of is:

select the block
of terminal text
and click the
</> icon
in the editor's toolbar

:wink:

Another issue (since when I migrated from Plasma X11 to Plasma Wayland, earlier this month):

Often, apps will try to launch a link in a web browser, but it will simply not work and nothing will happen. I’ve seen this behavior in Audacity, in some other GUI applications that I don’t remember right now, and now in the Pacnew Checker dialog.

In fact, from the commandline, I get this:

$ xdg-open https://example.com/
qt.qpa.services: Failed to register with host portal QDBusError("org.freedesktop.portal.Error.Failed", "Could not register app ID: App info not found for 'org.kde.kioclient'")

Potentially related to this, but I haven’t tried any solution yet.

I’m using junction as the default application for handling URLs.

Thank you the update, It went through without any problems and smoothly at my Desktop and other good Notebook .

That’s why I decided to switch my really old other notebook, with its cracked display and thick, round black dot, to the testing branch using remote maintenance via TigerVNC. Even there, everything runs quite well, just very slowly.

Thank you very much and Merry Christmas later on :evergreen_tree: :santa_claus: :christmas_tree::wrapped_gift:

Greetings

Tony

The following has been suggested:

  • 570xx for Desktops
  • 575xx for Laptops

Whether that extends to hybid/prime, I can’t say.

Same for me on KDE Plasma.

Running Timeshift from the command line using

$ sudo GTK_THEME=Breeze-Dark timeshift-gtk

fixes the appearance temporarily.

For a permanent fix, copying this config file seems to do the trick:

# mkdir -p /root/.config/gtk-3.0
# cp /home/user/.config/gtk-3.0/settings.ini /root/.config/gtk-3.0
