[Bug 1366708] Re: unattended-upgrade crashed with SystemError in open(): E:Problem renaming the file /var/cache/apt/pkgcache.bin.guEChP to /var/cache/apt/pkgcache.bin - rename (2: No such file or directory), W:You may want to run apt-get update to correct these problems

 

We had this issue for some time now (cf.
https://phabricator.wikimedia.org/T92491); I found bug #1091137 which
says:

| When the landscape-client runs apt-get update, it can return an error
like this:

| E: Problem renaming the file /var/cache/apt/pkgcache.bin.PGPOhV to /var/cache/apt/pkgcache.bin - rename (2: No such file or directory)
| W: You may want to run apt-get update to correct these problems

| This can happen if someone is running apt-get clean, while the update is happening. apt-get clean
| removes all pkgcache.bin files, including the temporary ones that apt-get update uses
| to rebuild the cache. This error is harmless, since pkgcache.bin should also have been
| removed, and thus the next time the cache will be opened the cache will be rebuilt.

| I.e, we should ignore the error above as to not cause intermittent alerts in the Landscape
| server, that the user can't do anything to resolve.

So my reading is that apt-get clean removes temporary files of another
process, and it shouldn't do that (IMHO).
