When I get this sorted I'll post the lot together as a clean post - or perhaps in the wiki or maybe as a TKLPatch 

So I posted on the GitLab mailing list and found out that things have changed a little...

Instead of 

sudo -u gitlab bundle install --without development test

you need to run

sudo -u gitlab bundle install --without development test postgres sqlite

which has got me further, but still not quite there, now I am stuck at the final step

sudo -u gitlab bundle exec rake gitlab:app:status RAILS_ENV=production

But it's definately there (I copied it there and chowned it to git:git as per instructions)

I have posted again on the GitLab mailing list but if anyone here has any bright ideas, I'd love to hear them....

[update] I have fixed this issue too now (it is to do with the permissions). Unfortunately I don't have my notes handy, but it's pretty straight forward. Unfortunately it still isn't working... :( It passes all the tests but the GitLab server still refuses to start... I think I'll start again on a fresh TKL GitLab appliance when I get a chance and see how we go from there...
