[Stonley890]

Same issue applies to 21.3. Perhaps it's a permissions issue? The updater does not request elevated privileges.

[Captain-Chaos]

It shouldn't need privileges. If you run it as a user it is installed under that user's home directory; if you run it as root it is installed globally (you could try whether that makes a difference).

The installer is generated by a third party tool so this is hard to debug for me, but I will inquire with them.

[Captain-Chaos]

I just noticed that you mentioned a .deb file, so this was installed using a .deb file originally? Then I don't think privileges apply; I'm not sure, but I think it is supposed to just download the .deb file, which you would then have to install manually.

[Stonley890]

That makes sense, but if everything works as expected, why does it throw an error? Should I file a report elsewhere if this is a third party tool?

[Captain-Chaos]

No idea. No that's not necessary; I'll do that.
