I have a similar error on Ubuntu 20.04 when refreshing or installing snaps like chromium, signal-desktop, etc.
Code:
:~/Downloads$ snap refresh chromium
Fehler: cannot perform the following tasks:
- Den Konfigurationshook von Snap "chromium" ausführen, falls vorhanden (run hook "configure": /snap/chromium/1479/snap/command-chain/hooks-configure-desktop: line 43: /snap/chromium/1479/gnome-platform/usr/bin/fc-cache: No such file or directory)
Any ideas? I tried all the answers i found like removing all font cache files and running
but without any success. Need help
