I've been able to replicate this issue with apt 1.9.0.2. Various Is the "apt-get update" call from which you have included the output a recent addition or was it 'always' there? I am asking as 'apt-cdrom add' actually does the work of copying the indexes to disk, which (should) mean that 'apt-get update' is a no-op, making the call useless if cdroms are really the only possible source in that stage. That 'update' isn't really supposed to be called here is reinforced by the ugly warnings/errors you showcase and which existed since ever. Our only testcase covering apt-cdrom also doesn't include such a call… Why that is the case, I have no idea, as I would expect at least some people to have multiple sources, including cdrom, which would call for an update, so that should really work without being scary (= assuming warnings from apt are regarded as scary…). The irony is that the suspected bad-boy 80174528 actually fixes this longstanding problem as the regression was that apt exited nonzero, not that it printed warnings (so much for scary). The problematic commit is b0f4b486 (and therefore not a regression in a security fix – everyone rejoice): While fine by itself, merged with the suspected bad-boy we still have no warnings and a successful exit, but our helpful list-cleanup kicks in removing files from the lists/ directory which seem to be orphaned given that it is looking e.g. for a Packages.gz file and not for Packages as the part fixing up the filename is skipped if a cdrom source is encountered. The attached patch should merge both in a better working way, at least that is what the testcase is promising me – which I have extended a bit to cover a bit more ground, too. Nothing near proper testing though, so someone giving it a proper testspin would be nice, but if that is too hard I guess Michael could just upload it and let the world test it for us (now that he doesn't have to fear another security upload). ;) Best regards David Kalnischkies

don't cleanup cdrom files in apt-get update
Regression from merging 801745284905e7962aa77a9f37a6b4e7fcdc19d0 and
b0f4b486e6850c5f98520ccf19da71d0ed748ae4. While fine by itself, merged
the part fixing the filename is skipped if a cdrom source is
encountered, so that our list-cleanup removes what seems to be orphaned
files.
