Downloads

Debian packages

For Debian, use the following APT source and apt install kavoom:

deb http://non-gnu.uvt.nl/debian stretch uvt
deb http://non-gnu.uvt.nl/debian bullseye uvt
deb http://non-gnu.uvt.nl/debian buster uvt
deb http://non-gnu.uvt.nl/debian stretch uvt
deb http://non-gnu.uvt.nl/debian jessie uvt
deb http://non-gnu.uvt.nl/debian wheezy uvt

You need to add all these lines, up to and including the version of Debian that you use, in the order as above. So if you're still on Debian buster, omit the bullseye line.

You may need to download the necessary GnuPG key and place it in /etc/apt/trusted.gpg.d.

Ubuntu

Ubuntu 20.04 and up will work as above. For 18.04 omit the bullseye line.
