[Bug 1950859] [NEW] Ubuntu installation failure - Vaio Nvidia and RAID connected to the problem

At first, impossible to install Lubuntu 15 on a Sony Vaio PCG-31111M.
By suppressing the RAID0 of 4 SSD 64Gb, I could install on the disk0. But still very unstable system.
Then by acting on the TPM in the BIOS, a first installation was done. The TPM actions where first a CLEAR, then a ENABLED.
In the internet comments, some people were speaking about the Nvidia processor. So I installed the Nvidia pilot (a Nvidia native pilot, but approved by Ubuntu) and finally, a first installation of Lubuntu 15 was done.
But It's impossible to install something better, like Ubuntu 20 for example. The installation keeps crashing at the end.
For unknown raisons, the wifi pilot was lost, and impossible to restore it.
