Comment 2 for bug 2003592

Hello, and sorry for the slow reply here.

You may have removed the Firefox snap, but it seems you had not removed the firefox deb helper package (it provides some useful system integration for the Firefox snap), and the pre-inst script of that package was the cause of error here.

If you still have access to that system, please also try removing the firefox deb package if you indeed don't use firefox.

Otherwise, the issue I see in the dpkg terminal logs is a temporary failure in name resolution (DNS lookup error), and was most likely a random/temporary issue that has since long been fixed, and there isn't much we could do for that from Firefox's perspective anyway. So I'll close this bug accordingly. Thanks.
