[Bug 1843606] Re: command-not-found unable to open database file (because it is readable only by root)

[Sergio Callegari]

My feeling is that the file permissions are changed whenever apt
installs something on the system. Is apt running some update script with
a wrong umask?

Title:
  command-not-found unable to open database file (because it is readable
  only by root)

Status in command-not-found package in Ubuntu:
  New

Bug description:
  On Ubuntu 19.04 I repeatedly encounter command-not-found crashing
  because it is unable to open its database.

  Inspection reveals that files in /var/lib/command-not-found are owned
  by root and have permissions set so that they are readable only by the
  owner.

  Deleting these files or changing their permission to be universally
  readable fixes the issue.
