I’m using Ubuntu 20.04.
I installed Root following the steps written into the website. When I try to launch root, this message compares:

You try to use a ROOT binary distribution for “Ubuntu 18.04 / GCC 7.5”,
It will not work on “Ubuntu 20.04 / GCC 9.4”.

The ROOT Team provides ready-to-use binary distributions for some systems (see “Download a pre-compiled binary distribution” therein), including various Ubuntu versions, which you just need to download and unpack.

For Ubuntu 20.04 / x86_64 / GCC 9.4: https://root.cern/download/?C=M;O=A;P=*[uU][bB][uU][nN][tT][uU]*20*
