Continuing the discussion from Eos-update-notifier not working:
upadting to latest welcome app will bring in endeavouros-theming package and will fail on some installations caused by some files already existing in filesystem.
simple remove this files… we have them before copied to system, no we ship them inside a package:
sudo rm /usr/share/endeavouros/EndeavourOS-icon.png sudo rm /usr/share/endeavouros/EndeavourOS-logo.png sudo rm /usr/share/endeavouros/splash.png
then do updating will work.
