[Bug 1692235] Re: Syntax error in .postinst - broken package

[fermulator]

"Android Dev" over on the Ubuntu forums posted
 - https://askubuntu.com/questions/917395/grub-post-installation-fails/917423#917423

It is pointed out there that in fact there is a semi-colon missing here! didn't see it myself
{{{
if dpkg --compare-versions "$2" lt-nl 2.02~beta2-36ubuntu3.10 then
                                                             ^
                                                             ;
}}}

After adding it, I can too confirm it resolves the syntax error.

Title:
  Syntax error in .postinst - broken package

Status in grub2 package in Ubuntu:
  Fix Released

Bug description:
  Apport doesn't allow the upload, because it's a known error.
  Since I never had an issue I'd like to report the multiple syntax errors in the .postinst file of grub-pc.
  Terminal output excerpt:
  sudo apt upgrade
  0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
  1 not fully installed or removed.
  Setting up grub-pc (2.02~beta2-36ubuntu3.10) ...
  /var/lib/dpkg/info/grub-pc.postinst: line 703: syntax error near unexpected token `fi'
  dpkg: error processing package grub-pc (--configure):
   subprocess installed post-installation script returned error exit status 2
  Errors were encountered while processing:
   grub-pc
  E: Sub-process /usr/bin/dpkg returned an error code (1)

  I've started to fix grub-pc.postinst step by step, because after
  removing the 'fi' in line 703 there occur more and more til line 740,
  e.g. semicolons, brackets and at the end it says unexpected end of
  file, which I was unable to fix, original it says exit 0. I've tried
  several inputs, looked at examples of other .postinst files, but
  nothing worked.

  Renaming /var/lib/dpkg/info/grub-pc.postinst and reinstalling grub-pc
  didn't help.

  dpkg --configure -a 
  and
  dpkg-reconfigure <package>
  didn't help.

  It would be nice if someone could fix the syntax. Thanks!
