package redmine 3.2.1-2 fails to upgrade: subprocess installed post-installation script returned error exit status 1

[Arne Ruhe]

SYMPTOM:
dpkg-configure fails when updating redmine to version 3.2.1-2 (Ubuntu 16.04) due to a missing Gemfile.lock in /var/lib/redmine/
Gemfile.lock does exist, but is locates at /usr/share/redmine/

ERROR (same error as when using apt update):
$ sudo dpkg --configure redmine
Setting up redmine (3.2.1-2) ...
chown: cannot access '/var/lib/redmine/Gemfile.lock': No such file or directory

I have the same problem.

Even though I copy Gemfile.lock from /usr/share/redmine/ to /var/lib/redmine/, it doesn't help.

Status changed to 'Confirmed' because the bug affects multiple users.

Same output when dpkg --configure redmine for me.

Same on Debian (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=838555 )

I also have the same problem.
In the absence of resolution. Would someone please give a workaround for amateurs ?

Hello, I followed:

http://www.redmine.org/boards/2/topics/40180

Pasting the message here:
------------------------------------
Here is how I fixed the problem. I'm on Ubuntu 12.04 LTS server:

To fix the first problem:
sudo gem install bundler
To fix the second problem:

    sudo touch /usr/share/redmine/Gemfile.lock
    sudo chown www-data:www-data /usr/share/redmine/Gemfile.lock

I hope this helps. Ideally the best thing is to move the Gemfile.lock somewhere else in the configuration but this solution is minimally invasive on the ubuntu package.
------------------------------------

then I run apt-get upgrade the Gemfile.lock, while continously watching over the Gemfile.lock. And it turns out Gemfile.lock disappears during the upgrade - *before* the apt get finishes with and error exit status

Solution found here (https://stackoverflow.com/questions/45757459/redmine-3-2-1-2-ob-ubuntu-16-04-breaks-on-apt-upgrade), was to comment out line 12 of script /var/lib/dpkg/info/redmine.postinst:

#chown www-data:www-data /var/lib/redmine/Gemfile.lock
