Test of Ubuntu 20.04 on Linux login server lilo7

As a test of the new version of Ubuntu, 20.04 LTS, we have installed a new login server lilo7.science.ru.nl. In a few months it will replace the four year old login server lilo5. The name lilo, that always points to the newest/fastest login server, will then be moved from the more than two year old lilo6 to the new lilo7. The new lilo7 is a Dell PowerEdge R7515 with 1 AMD 7502P 2.5GHz 32-core processor and 64GB RAM. Because we enabled hyper-threading, it is showing 64 processors. For users who want to check the identity of this new server before supplying their Science-password to the new server, see the section about our loginservers. Please report all problems with this new version of Ubuntu Linux.
