error update from Ubuntu 20.04 to 22.04 on Raspberry Pi 2B

[G H]

The attached error was generated while I was trying update my Raspberry Pi 2B from Ubuntu 20.04 to 22.04. It somehow appears to be related to firefox. (In the upgrade from 20.04 to 22.04, the firefox debian package appears to be removed in favour of a snap package, but I don't know if this is what causes the error.)
