As a work around, I notice that Freemind is made available via a snap package in the GNOME Software center.
I installed freemind with this command: snap install freemind It launched a little slow, but came up, I was able to open the mind map I was needing using freemind. However, it did prompt me that my map was created in an "older version", so I did have approve converting it to a newer version before opening it and it warned that I would not be able to open it older versions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826867 Title: Freeplane Freezes Immediately After Launching It To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/freeplane/+bug/1826867/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
