[DRE-maint] Bug#845935: gitlab postinst fails

[Johannes Schauer]

Package: gitlab
Version: 8.13.3+dfsg1-2
Severity: normal

Hi,

when upgrading my gitlab 8.8.2+dfsg-5 to 8.13.3+dfsg1-2 I encountered
the following error during package configuration:

Using health_check 2.4.0
Using jquery-turbolinks 2.1.0
Using devise-two-factor 3.0.0
Bundle complete! 135 Gemfile dependencies, 244 gems now installed.
Gems in the groups development and test were not installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

It is not obvious to me what to run with "--trace". Would you like a
separate bug about adding some more helpful output to the postinst?

After reading the postinst script, I assumed that what failed was
rake-tasks.sh:

$ /usr/lib/gitlab/scripts/rake-tasks.sh --trace
gitlab_production database is not empty, skipping gitlab setup
Precompiling assets...

But the last line of the output suggests that I'm supplying --trace to
the wrong process again...

Thanks!

cheers, josch
