Public bug reported: This happens on a 20.04 LTS (Focal Fossa) beta system, specifically, the xubuntu-20.04-beta-desktop-amd64.iso as downloaded on Apr 14.
When sshing into the 20.04 system, from the previous LTS (18.04), entering/exiting insert mode in vi emits what looks like CSI>4;m resp. CSI>4;2m. Both sequences aren't recognized by the 18.04 terminal, resulting in garbled output and vi being unusable. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872896 Title: terminfo file xterm-256color has entries that make vi unusable when sshing in from last lts (18.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1872896/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
