Suddenly Skanpage won't show up in Plasma 5.27.12

rumplin · March 25, 2025, 5:25pm

I suddenly can’t open Skanpage anymore, it was installed trough the Ubuntu 23.08.05-0ubuntu4 repo. It worked before, but now (after updates?) it doesn’t anymore.

I uninstalled the app and installed it trough Snap 24.12.1 repo.

Still not showing up (note, the app starts when I start the one from Ubuntu repo, but the window does not show).

My system:

and the processes hang and make my laptop go hot:

johnandmegh · March 25, 2025, 6:12pm

Hi! I’m not currently a Kubuntu user, but based on the large number of AppArmor errors in those logs, I would suspect there’s some profile issue there - ex. it looks like both sets of logs are using a Snap AppArmor profile?

This likely would need checked out by the Ubuntu / Kubuntu folks, since the packaging and AppArmor profiling and all of that would typically be done downstream at that distribution level: Help and Support | Kubuntu

skyfishgoo · March 25, 2025, 6:42pm

i’m a kubuntu user and i’m curios why you are running an older kernel.

what are the outputs of these two command lines?

ls -1 /boot/vm*

and

apt list --installed linux-hwe* linux-image* linux-mod* linux-head* linux-gen*

dzon · March 25, 2025, 6:49pm

Isn’t 6.8 the default kernel in 24.04?

It’s default. I haven’t changed anything from the default installation.

rumplin · March 25, 2025, 9:30pm

I’ll setup a Virtual Machine and check there if it starts up, other than that I suspect that an update broke the app.

Just did a fresh install in a VM, and it’s also on Kernel 6.11.
Seems that something went wrong at mine, I’ll probably just reinstall the whole system from scratch.

skyfishgoo · March 26, 2025, 2:03pm

whoa, that seems harsh.

before you ditch your current install i would just try installing the hwe package and let it update.

sudo apt install --install-recommends linux-generic-hwe-24.04

I just finished the update (Kernel).

unfortunately, it didn’t fix the issue with Skanpage:

The process for Skanpage was running, but not showing the window. So I send the Termination command for the process.

rumplin · March 26, 2025, 3:47pm

wondering if this line has anything to do with this:

|26. 03. 25 16:42|plasmashell|qrc:/qml/DocumentPage.qml:14:1: module org.kde.kquickimageeditor is not installed|

ngraham · March 26, 2025, 4:04pm

Yes, that’s the problem. The app is missing a dependency.
