Very similar to this topic:
Everything seems to work but the project homepages.
I use the omnibus package on Debian Jessie and wanted to upgrade vom 7.12.2 to 7.13 but I get another error (see at the end of the post). I can reproduce the error by calling sudo gitlab-rake db:migrate. Here are the last few lines of gitlab-rake db:migrate:status:
up 20150516060434 Add note events to web hooks
up 20150529111607 Add user oauth applications to application settings
up 20150529150354 Add after sign out path for application settings
down 20150609141121 Add session expire delay for application settings
up 20150610065936 Add dashboard to users
down 20150620233230 Add default otp required for login value
down 20150713160110 Add project view to users
down 20150717130904 Add commits count to project
This is the error:
