This has been fixed in a new Debian Release (2.2.7+dfsg-1). Tested a package built on Focal and these warnings go away.
Specifically they added two patches: 0006-Fix-warnings-for-ruby-2.7.patch 0007-Fix-more-warnings-under-ruby-2.7.patch Since this is in universe but a popular too, hoping we can sneak in a Debian sync for Focal with the new version as well to fix this otherwise I can look to submit a patch for the warnings specifically. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871685 Title: vagrant spits out ruby deprecation warnings on every call To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vagrant/+bug/1871685/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
