Description:

Vagrant is not technically compatible with ruby version 2.7, which was introduced last month.

See the gemspec: https://github.com/hashicorp/vagrant/blob/58687e6c4485790670fead7b579e3a1a60927b77/vagrant.gemspec#L15

s.required_ruby_version = "~> 2.4", "< 2.7"

I'm not sure if there's a way to address this without downgrading the version of ruby installed but it displays a significant number of deprecation warnings as-is.


Additional info:
* package version(s):
- Vagrant 2.2.7
- Ruby: ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux]
* config and/or log files etc.
