That's a good question. I'm not sure of the exact history of these systems, but I'm under the impression that they've gone through dist- upgrades from as least one older LTS and more likely at least 2 (i.e. from 16.04 to 18.04, to 20.04), but that predates my involvement. That said, when I looked at the ones prior to the upgrade, the file in /usr/sbin had the same May (I think) 2020 timestamp as the /sbin copy, so it perhaps was a hard link that failed to get upgraded by the package update.

Orphaned older executable breaks docker Status in apparmor package in Ubuntu: Confirmed Bug description: There appears to be two copies of apparmor_parser installed by previous versions of the apparmor package, in /sbin and /usr/sbin. When updating the apparmor package to apparmor-2.13.3-7ubuntu5.2, only the /sbin/apparmor_parser executable is updated and the /usr/sbin copy is left unchanged. Being earlier the path, /usr/sbin/apparmor_parser is used by Docker when trying to register the docker-default apparmor profile for containers. The orphaned older executable reports a warning about a new parameter in the parser configuration file in the same package, and that warning breaks the version check that docker runs against that executable on the first line of output. trying to parse the warning while looking for the version number results in the error: docker: Error response from daemon: AppArmor enabled on system but the docker-default profile could not be loaded: strconv.Atoi: parsing "file": invalid syntax. As a workaround, we've been replacing the old version in /usr/sbin with a symlink to the file in /sbin, but the package should be corrected to do appropriate behaviour (either delete the unnecessary(?) copy in /usr/sbin or replace it with a symlink) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2017594/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
