[Bug 1786821] Re: pam.7.gz is a symlink to PAM.7.gz . This does not work for caseinsensitive filesystems e.g. Windows Subsystem for Linux

[Markus Werner]

Hi Balint,

dpkg -i libpam-runtime* will throws an error cause it trys to symlink pam.7.gz to PAM.7.gz since Windows filesystem is case*in*sensitive this both files are the same and so the symlink will get refused cause the file already exists.
So apt upgrade won't work on Windows. Maybe there is also a Windows way to upgrade Windows Subsystem for Linux (WSL) but since apt tools are working it should be fix IMHO.

So if there is no reason behind "PAM && pam"  it would be good if it
will be removed. If there is a reason maybe the postinstall scripts
could generate the symlink after checking that it is a casesensitive fs.

Thanks for the msdn link. I will check if it works. This might be a
solution, cause other linux packages might have the same issue.

Markus

Title:
  pam.7.gz is a symlink to PAM.7.gz . This does not work for
  caseinsensitive filesystems e.g. Windows Subsystem for Linux

Status in pam package in Ubuntu:
  Incomplete

Bug description:
  The package libpam-runtime contains a symlink pam.7.gz -> PAM.7.gz in
  ./usr/share/man/man7 and this doesn't work in Windows Subsystem for
  Linux since Windows has a caseinsensitive filesystem.

  On ubuntu 18.04 this PAM.7.gz exists too. I know it's not a linux
  centric issue. But why libpam-runtime is using Uppercase and symlinks
  anyway? Other packgages in man7 just use lowercase, and this is what
  I'm expecting.

  Hopefully you can fix it.
