Oh, what an impedance mismatch!
@neo75, let me try to translate the recommendations:
- Check for full filesystems in Settings->Storage or by executing
df -h
If there is only little space left (denote where?) you have to (re)move stuff (you may ask “what?”, when you reported what you see).
Lastly test if apkcon refreshworks. - If not, try removing the Zypper cache (reference, e.g., URL scheme is a required component): It is just a cache, you may simply remove it by executing
devel-su rm -rf /home/.zypp-cache/*
Then test if apkcon refreshworks.
HTH
