Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Error from log

Postfix is now set up with a default configuration. If you need to make
changes, edit
/etc/postfix/main.cf (and others) as needed. To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

Hi Roman

Thanks for taking the time to report this bug and helping to make Ubuntu better.

Looks like you system was not configured with a valid hostname and domain name - as a result the postfix configuration is broken which is why you keep seeing this issue.

You can fix this by editing /etc/postfix/main.cf - look for the myhostname parameter; run the following commands in a terminal to fix the file and then complete the installation.

  sudo vi /etc/postfix/main.cf
  sudo dpkg-reconfigure postfix
  sudo apt-get -f install

or you could configure your system with a valid host and domain name - but that is a little more complicated.

If this resolves your issue please mark the bug report as 'Invalid'

Thanks
