[Impact] Because update-notifier does not explicit have the `lsb-release` package as a dependency, users may install the package and rely on `apt-cdrom-check` to work, but it will fail, since it runs the `lsb_release -sr` command on it.
[Test case] To reproduce the issue: 1. Launch a xenial container 2. Install update-notifier on it 3. Run apt-cache depends update-notifier-common 4. Verify that lsb-release does not appear To verify that the error is fixed: 1. Install the new update-notifier from this ppa: https://launchpad.net/~lamoura/+archive/ubuntu/update-notifier-test-ppa/ 2. Run apt-cache depends update-notifier-common 3. Verify that lsb-release will now appear as a dependency [Where problems could occur] We are only adding a missing dependency to the package. I cannot think of a problem that this might cause to the users of this package. [Discussion] We can verify that `apt-cdrom-check` does make use of the `lsb_release` command. Since we don't have that dependency on the package control file, errors can appear when users are executing/relying on that script. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927996 Title: /usr/lib/update-notifier/apt_check.py:FileNotFoundError:/usr/lib /update- notifier/apt_check.py@16:check_output:run:__init__:_execute_child To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/1927996/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
