Manjaro/Arch - Octopi will not fire.

Postby viking60 » 03 Feb 2016, 17:21

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 :berserkf what exactly am I to install? :confused
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. :jackpot

So the lesson is: Removing orphans is true Berserk stuff that needs you to be awake :berserkf ... and checking the cache (chicken stuff) to fix the fubar is the medicine :oops:
Manjaro 64bit on the main box -Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz and nVidia Corporation GT200b [GeForce GTX 275] (rev a1. + Centos on the server - Arch on the laptop.

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.
