** Project changed: auto-package-testing => postfix (Ubuntu) ** Summary changed: - Domain name for autopkgtests ending with dot ('.') + Installation fails with fully qualified domains (w/ trailing dot) -- You received this bug notification because you are a member of Canonical's Ubuntu QA, which is subscribed to Auto Package Testing. https://bugs.launchpad.net/bugs/2019195 Title: Installation fails with fully qualified domains (w/ trailing dot) Status in postfix package in Ubuntu: New Bug description: I have been looking at https://autopkgtest.ubuntu.com/results/autopkgtest-mantic/mantic/amd64/f/fwlogwatch/20230502_145023_da50b@/log.gz where the installation of postfix fails in the autopkgtest environment. The hostname passed to the test is "adt-mantic- amd64-fwlogwatch-20230502-143927-lrg-root5". After concatenating with the domain in postfix function check_myhostname() the hostname becomes "adt-mantic- amd64-fwlogwatch-20230502-143927-lrg-root5.openstack.prodstack5.lan." which terminates with a dot. Later function valid_hostname() detects that this is invalid. As the problem does not occur in a local autopkgtest I assume this is due to some issue with the openstack configuration.
