[Tex/LaTex] Installing LyX 2.3.0 on Ubuntu 18.04, Bionic – Repository does not have a release file

lyxUbuntu

I tried installing LyX 2.3.0 following the instructions I found here, but I got the error message that 'The repository does not have a release file' so apt-get won't let me add it.

My other laptop is running Ubuntu 16.04 and I didn't have this problem, and it's quite annoying since I have a bunch of LyX documents written on the 2.3.0 version which can't be opened by the latest addition available in Ubuntu's repository.

Tried on July 2018, with Ubuntu 18.04.1 LTS, and it worked without issues. I just did as per the doc:

  1. sudo add-apt-repository ppa:lyx-devel/release
  2. sudo apt-get update
  3. sudo apt-get install lyx
