My understanding now is that the resolver *tolerates* search domains starting with a ".", stripping it off. This is very visible in the code snipped posted by Sergio:
if (dname[0] == '.') dname++; and this is the reason "search ." is not really documented: it's not really useful as in practice it is not different from having no search domain at all. However, given that "search ." is for some reason not that rare, I think it makes sense to make the postfix postinst script tolerate it. The fix only requires a small change in a regexp. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1906970 Title: dpkg hook hostname error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1906970/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
