Colord: mapping.db not found

Hi,
Artix/Plasma/runit, I'm trying to use colord with colord-runit and colord-kde (I also installed the ICC profile for my monitor through Plasma).

Colord does not start at boot, with the error:
Code: [Select]
CdMain: failed to load mapping database: Can't open database: unable to open database file

Tried to run it manually with sudo chpst -u colord /usr/lib/colord --verbose, I got:
Code: [Select]
Verbose debugging enabled (on console 1)
CdMappingDb: trying to open database '/var/lib/colord/mapping.db'
CdMain: failed to load mapping database: Can't open database: unable to open database file

Then I checked, and the directory /var/lib/colord does not exist, searched for a mapping.db file on the whole filesystem and it does not exist, so... How am I supposed to create it?

I can't use colormgr because, as colord isn't running, it fails with the error
Code: [Select]
No connection to colord: Error calling StartServiceByName for org.freedesktop.ColorManager: Launch helper exited with unknown return code 1

opened pamac and searched for colord.  colord does not provide a file on install to that location or such a named file db.  Same is true for colord-runit and colord-kde.



You didn't install one of these from the aur?  Nothing in the repos for artix should even be installed to such a directory or such a db file.

have you installed arch repos maybe and put them in pacman.conf out of order?

Ok, so how should I generate this file/otherwise solve the error?

None of these packages is from the AUR

No (?)

you could open a terminal and create the path and the file as root user but i wouldn't expect much from that.  Crazy as it sounds it might just work.

If you use pamac you could look and see what repo you installed colord and the others from.  My first thought is you installed something from a repo other than artix.

I configured the repositories as in the wiki, so that Artix ones take precedence , and apparently Colord is not in Artix repos. I checked with Octopi, and colord has been installed from Arch's extra repository

EDIT: colord is in Artix repos and I reinstalled it from world, but the problem is the same

search the web for the error
Code: [Select]
CdMappingDb: trying to open database '/var/lib/colord/mapping.db'
and see what you find?


Also, diod you reboot after installing colord?

Nothing useful, as most question do not have a reply, or are related to an existing but corrupted mapping.db, while here I don't have such a file nor I do find instructions on how to create it

did you try rebooting after installing colord?

Perhaps the error is with artix after all?  Maybe the app wasn't built properly since the files it generates don't include the db file?  But according to the post above it seems colord is making the file when it runs as someone had a corrupted file and deleted it in order to fix the corrupted file.

I'll open an issue

Additional detail: now I remembered that I had to create the folder manually, as at first it gave Error creating directory /var/lib/colord: Permission denied, so I tried to chmod 777 the folder and now colord works.

Obviously it is NOT a solution, but a workaround, I'll have to understand what's happening

Artix Devs will create the fix.  Clearly colord needs to write to a directory it doesn't have permissions for.  They can do that and rebuild the package.  Meanwhile everyone has your workaround thanks to your efforts.

Thank you, is there a procedure to notify the devs?

By the way, I want to highlight that probably this is not the best solution, 777 permission should be used with caution...
