[Bug 1767523] Re: Upgrade from Mate 17.10 failed due to Xwindows problem now dosn't install from 18.04 pendrive

[Carlos Sevcik]

Even my previous tips produced a buggy result I finally got UM 18.04
working as follows.

1-Clean install 17.10 with a wipe everything option (Phony enough this
did erase my previous / and /home ext4 partitions). Let it install the /
partition in 14 GB /dev/nvme0n1p1 ext4. Let the installation finish
undisturbed.

2-Reboot the machine with the UM 17.04 installer. And choose "Do
something else". Define a new / and /home partitions if, as it was my
case, tour old / exists as the installation to format the partition ext4
(100 GB ext4 in my case) and IGNORE COMPLETELY /dev/nvme0n1p1 DO NOT
MODIFY IT IN ANY WAY. If your old /home partition exists (900 Gb in my
case) use it as ext4 (or whatever is your partition format) AND DO NOT
FORMAT IT IF YOU WANT TO PRESERVE YOUR DATA. Let the re-installation
finish undisturbed. DO NOT INSTALL THE NVIDIA PROPRIETARY DRIVES at this
stage. Fully update UM 17.10 from the repositories.

3- You should get a notice that a new UM exists, this is UM 18.04,
follow the automatic procedure to update 17.10 to 18.04 from Ubuntu
Internet repositories, when this finishes, reboot to UM 18.04.

My system now runs fine except for an error at login indicating that a
notification area in the panel crashed, I restart it as suggested and
then things are OK. I cannot lock my account though, it locks and
unlocks fine if I leave the system undisturbed for some 10 min and then
come back to use the machine.
