[Debian native package] help with upgrade from 13.6 to 13.7 failing with Feature::InvalidFeatureFlagError: Feature flag 'api_kaminari_count_with_limit' is al ready defined in '/usr/share/gitlab/config/feature_flags/ops/api_kaminari_count_with _limit.yml'
Originally reported here https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=983346 and has details of what I already tried.
It appears to be as caused by now obsolete flipper.rb initializers. We were manually removing files in config directory as config directory gets installed as /etc/gitlab and config files are not removed automatically on upgrades.
So flipper.rb should have been removed in 13.6 but it was not removed which did not through an error in 13.6 but now causing error in 13.7 I tried removing it now and also checked and removed all obsolete initializers (will more proactively check for this in future).
Any ideas how to fix this now? Can we revert the changes done by config/initializers/flipper.rb?
