I did a package search for jack.

and find that it is not available on Ubuntu 20.04.

Is it not required on Ubuntu 20.04 to connect audio devices? If required how can I backport?

  • That package relied on python(2) which has been removed due to python 2.x being EOL. It needed to be ported to python3 for it to remain (packages.ubuntu.com/eoan/jack) – guiverc May 5 '20 at 5:15
  • Just because I am curious: I remember that that Jack used to be bundled with Ubuntu Studio and I checked with apt-cache policy *jack* when running Ubuntu Studio persistent live: it is ported to Ubuntu Studio 20.04. You can use that or install it the same way. – sudodus May 5 '20 at 14:03

You can still install it using packages from Ubuntu 18.04 LTS:

cd ~/Downloads
wget http://archive.ubuntu.com/ubuntu/pool/universe/p/pygtk/python-gtk2_2.24.0-5.1ubuntu2_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/main/p/python-pathlib/python-pathlib_1.0.1-2_all.deb
wget http://archive.ubuntu.com/ubuntu/pool/universe/e/eyed3/python-eyed3_0.8.4-2_all.deb
wget http://archive.ubuntu.com/ubuntu/pool/universe/p/python-cddb/python-cddb_1.4-5.3_amd64.deb
wget http://archive.ubuntu.com/ubuntu/pool/universe/j/jack/jack_3.1.1+cvs20050801-29.2_amd64.deb

sudo apt-get install ./python-eyed3_0.8.4-2_all.deb ./python-gtk2_2.24.0-5.1ubuntu2_amd64.deb ./jack_3.1.1+cvs20050801-29.2_amd64.deb ./python-cddb_1.4-5.3_amd64.deb ./python-pathlib_1.0.1-2_all.deb
