Could you please post AppArmor denial logs generated by os-prober?

Title:
  os-prober is broken on Questing due to apparmor misconfiguration

Status in apparmor package in Ubuntu:
  New
Status in os-prober package in Ubuntu:
  New
Status in rust-coreutils package in Ubuntu:
  New

Bug description:
  os=prober fails to function Questing.

  It appears that apparmor blocks temp directory creation (mktemp from
  rust-coreutils) in context of os-prober.

  Just renaming os-prober script to anything else allows it to function.
