------- Comment From boris.m...@de.ibm.com 2021-08-26 13:23 EDT------- Problem could not be reproduced by Canonical. Further detailed information requested by Canonical was not provided to them since May. In the meantime, the new point release Ubuntu Server LTS 20.04.3 is available. This means that 20.04.2 which the bug was opened against, has become obsolete. Therefore, closing / rejecting the bug.
