Error updating r10k to v. 3.7.0 on Centos 7: "cri requires Ruby version >= 2.5."

[gdubicki]

Describe the Bug

[root@puppetmaster:~]# /opt/puppetlabs/puppet/bin/gem install -v 3.7.0 r10k
ERROR:  Error installing r10k:
        cri requires Ruby version >= 2.5.

Expected Behavior

It should update.

Steps to Reproduce

1. Have r10k 3.3.1 and cri 2.6.1.
2. Run /opt/puppetlabs/puppet/bin/gem install -v 3.7.0 r10k

Environment

Puppet: 5.5.22

/opt/puppetlabs/puppet/bin/ruby --version
ruby 2.4.10p364 (2020-03-31 revision 67879) [x86_64-linux]

CentOS Linux release 7.5.1804 (Core)

Additional Context

I did work around this with updating cri to 2.15.6 first and then updating r10k.

But the same r10k update worked on our test puppetmaster in December without such workarounds.

I guess that r10k doesn't pin the cri package version so when updating it tries to install the latest cri which is incompatible with ruby 2.4 bundled with Puppet 5.5. I suppose that pinning the cri version should help.

Hi @gdubicki, thanks for opening this issue! It looks like cri dropped support for old versions of Ruby in a Z release in December.. 😒

The current version of r10k allows using cri 2.15.10, which is the last version to support the old Ruby versions, so you should be able to continue using it.

I will look into getting this fixed, but we plan to drop support for Ruby < 2.5 in our next major release.
