Error in Abaqus 2020 installation on Ubuntu

Hi all,

I am trying to install Abaqus 2020 on Ubuntu 20.04, however, this error appears in the beginning of the installation procedure. Please advise to resolve it.

Error:

The installation of SIMULIA Established Products has failed. Do you want to launch it again, continue or abort the global installation?

Technical details:

Action LaunchMediaAction from feature CODE\linux_a64\AM_SIM_Abaqus_Extend.media failed.

Action ID: Launch_Media_SIMULIA_EstPrd.Linux64_5.2


And in the terminal, I see:

DSY_OS_Release="Ubuntu"
Unknown linux release "Ubuntu"
exit 8
