Redmine

I'm trying to setup redmine 4.2.3 on CentOS 8 with following setup:

ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x86_64-linux]
mysql 8.0
rails 6.1

#bundle install --without development test

[DEPRECATED] The `--without` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set --local without 'development test'`, and stop using this flag

..... (ignoring the normal output)
