@daiyam Any updates?

VSCode is still using core20 so I don't know what to do...

[daiyam]

Ok, they are still using core20 but it seems that they will soon be moving to core22.

Almost 1 year and still in use the old core20.

I cannot remove core20 because of this.

$ sudo snap remove core20
error: cannot remove "core20": snap "core20" is not removable: snap is being used by snaps codium
       and gnome-3-38-2004.

Visual Studio Code is still using core20

[qwertychouskie]

VSCodium still using core20 means I can't launch GUI apps from the built-in terminal, as it gives an undefined symbol error that seems related to glibc. Is there a reason that VSCodium needs to use the same outdated/deprecated dependencies that MS's packaging uses? For that matter, does core20 even get security updates anymore, given that it's based on an EOL version of Ubuntu?

The upstream snapcraft.yaml is here: https://github.com/microsoft/vscode/blob/main/resources/linux/snap/snapcraft.yaml

If someone familiar with the snap process adjusted this and made an upstream PR, perhaps it would get merged, and new upstream releases would actually use a modern core snap?
