Public bug reported:
proftpd 1.3.9~dfsg-4 on Ubuntu resolute
In resolute, apparmor ships a default enforcing profile for proftpd,
which seems to be just fine for old style FTP operations.
Unfortunately, it does not work as-is when mod_sftp is to be used, as
some of its actions (such as reading ssh host keys) are not covered in
the default profile.
A possible workaround until the apparmor profile can be adjusted might
be to switch it to complain mode.
