Error when trying to install on ArchLinux

Zen UV
1

register_class(…): already registered as a subclass ‘ZENUVLIST_OT_entry_remove’

Hi, it seems to be wrongly upgraded using Copy New Settings Blender option while upgrading to the highest version. The possible workaround:

  1. Uninstall addon (Remove)
  2. Restart Blender
  3. Install addon
  4. Restart Blender
3

No module named ‘imghdr’

4

ZenUV does not use any module with such name. And provide the full debug log file the next time, please

and if i restart blender and tries to activate it it just say

No module named ‘imghdr’

gonna see if i can generate a log file so you can see the actual debug stuff

My bad, I forgot that Checker system uses imghdr module. So you need to install this module manually using pip, because in Windows, Mac other Linux, it is deployed by default

7

I see that it is removed from Python 3.13 and seems that in your system Python version is different from other OS

Sorry, started issues because i was lazy and wanted to update blender through my system update so i installed it from repository.
now i installed the tar from the website which provide it’s own python instead of the system python, and then it works without issues.
