[Bug] All imported projects unaccessable after upgrading from 8.4.3 to 8.9.6.

I'm using the omnibus package and I've just updated Gitlab via sudo yum update. I had a number of projects I had imported from github and now I get a 500 whenever trying to view those projects. The error from the logs is:

OpenSSL::Cipher::CipherError (iv length too short):
  app/models/project.rb:456:in `import_url'
  app/models/project.rb:486:in `external_import?'
  app/models/project.rb:478:in `import?'
  app/models/project.rb:494:in `import_in_progress?'
  app/controllers/projects_controller.rb:93:in `show'
  lib/gitlab/middleware/go.rb:16:in `call'

I've verified that $RAILS_ROOT/.secret stayed the same and that /etc/gitlab/gitlab-secrets.json also stayed the same, although the gitlab-secrets.json file had some data added to it. What is the issue?

@maxggg do you know if $RAILS_ROOT/config/secrets.yml changed? I'm updating things at the moment to make sure all DB encryption keys are stored in there (currently some are still in $RAILS_ROOT/.secret) and update the corresponding docs, too.

The related issue: https://gitlab.com/gitlab-org/gitlab-ce/issues/3963

Yes, $RAILS_ROOT/config/secrets.yml is also the same.

By the way, I "fixed" this issue by deleting all import information from my projects. Here is the command I used:

sudo gitlab-rails runner "Project.where.not(import_url: nil).each { |p| p.import_data.destroy if p.import_data }"

Thanks, I was going to suggest something like that if the projects are already imported. @jameslopez I know you were fixing some things to do with imports lately, does this sound familiar?

Status changed to closed

Oh yeah, very familiar. Thanks for pinging @smcgivern - This is a duplicate of https://gitlab.com/gitlab-org/gitlab-ce/issues/19073

I'm gonna close this issue in favour of https://gitlab.com/gitlab-org/gitlab-ce/issues/19073
