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). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1366708 Title: 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 Status in unattended-upgrades package in Ubuntu: Confirmed Bug description: I get this after every session startup in Ubuntu Gnome 14.10 (currently dev) with Gnome 3 PPAs (noth main and staging added).
