Currently there is LyX 2.2.3-5 in Ubuntu 18.04 LTS (Bionic). There is discussion in https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/1595358 about getting 2.1.5 into 16.04 LTS (Xenial) and they claim 2.1.5 can read and write the file format of 2.2.x. If you have concerns about 2.1.5 not being enough, please leave a comment in that bug.
So perhaps this bug can be closed? ** Changed in: lyx (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602145 Title: [needs-packaging] LyX version 2.2.x should go into LTS (maybe backported?)
