TeXmacs ubuntu repository on Linux Mint

Hi,

I'm writing this in hopes that maybe this makes it onto the Installation=
=20
Instructions page:

To install the Ubuntu-Repository version of TeXmacs on Linux Mint you'd=20
have to use this command (the rest the same as with the original ubuntu=20
instructions)

echo "deb [signed-by=3D/usr/share/keyrings/texmacs-keyring.gpg]=20
http://ftp.texmacs.org/TeXmacs/tmftp/repos/apt/ $(cat /etc/os-release |=20
grep UBUNTU_CODENAME | cut -d"=3D" -f2) main"

which is the same as the original, but

cat /etc/os-release | grep UBUNTU_CODENAME | cut -d"=3D" -f2

instead of

lsb_release -cs

greetings and keep up the good work

Moritz
