Manjaro/Arch - Octopi will not fire.

[viking60]

Manjaro and Arch have this GUI frontend for pacman that suddenly stopped fireing

This application failed to start because it could not find or load the Qt platform plugin "xcb"

Well yeah great information there what exactly am I to install?
Reinstalling Octopi did not pull the needed xcb stuff either.

Then I remembered that I had removed my orphans

Code: Select all

pacman -Rs $(pacman -Qqdt)

So that would give me a clue.

Normally I think logs are for sissies but now I really needed to check what xcb stuff that was removed so I did a

Code: Select all

cd /var/cache/pacman/pkg/

After some "ls-ing" I found two xcb related entries there that were no longer installed:
xcb-util-cursor and xcb-util-renderutil

Well since that was in the cache and the only stuff named xcb something - the rest was easy:

Code: Select all

sudo pacman -S xcb-util-cursor xcb-util-renderutil

And oh wonder: Octopi fired just fine.

So the lesson is: Removing orphans is true Berserk stuff that needs you to be awake ... and checking the cache (chicken stuff) to fix the fubar is the medicine

Keeping the cache not cleared, or moving the files to an external drive from the cache is always a good thing. I do it with all my Linuxes.
If something is missing or not working properly, your hunch was right. auto orphans do it a lot.
Good job, as usual.

in manjaro you should use pamac

for comand line i prefer pacui + yay

[viking60]

I think Octopi is just fine especially if you are using QT5. But it is different from Pamac so a compare is not really "fair".
In Norwegian the Octopi translation is so much better than Pamac so that allone is reason to use it here.
