[Bug 1869320] Re: Could not install Ubuntu 16.04 on New AMD Ryzen 3900x with Asus TUF x570 Gaming Plus motherboard

[madbiologist]

Does this problem still occur with Ubuntu 16.04.7 LTS which was released
on August 13, 2020?

Note that Ubuntu 16.04.7 LTS was the last update to Ubuntu 16.04 and
official support for Ubuntu 16.04.7 LTS ended in April 2021.  It is
recommended that you update to a supported release such as Ubuntu
18.04.5 LTS or Ubuntu 20.04.2 LTS.
