Bug description:
  apparmor:5.0.0~alpha1-0ubuntu1 profiles have rules for gnu-coreutils
  binaries are incompatible with  gnu-coreutils v. 9.5-1ubuntu2 released
  on May 08, 2025.   Minimally this looks to affect wg-quick profile.
  But there may be other profiles that are affected.

  
  gnu-coreutils delivers new symlinks for /usr/bin/cat, /usr/bin/readlink and 105 other utilities in /usr/bin which point to /usr/bin/gnu<toolname>. Apparmor resolves the symlink to the real target path which then breaks any apparmor profile which referenced the format /usr/bin or /usr/sbin utility name.

  
  The result is many DENIED operations for any symlinked gnu-coreutils command.

  
  This bug appears to affect any apparmor profile in Ubuntu questing which happens to set file-based mediation rules for any of the symlinked utilities below:

  
  Any profile which has specific file rules related to these utilities will likely have DENIED messages in Ubuntu questing of the format: 
  pe=1400 audit(1757953283.765:489): apparmor="DENIED" operation="open" class="file" profile="wg-quick" name="/usr/bin/gnusort" pid=2480 comm="wg-quick" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
