Title:
package leaves non-updated copy of /usr/sbin/apparmor_parser after
update to apparmor-2.13.3-7ubuntu5.2. 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)
