Hi,
as the title suggests, I tried to install via the latest ( MATE and CINNAMON) ISOs but no sucess ...
I think that the installer is "Calamares" , or am I incorrect ?
The machine I has 8 devices, calling "lsblk" reports them correctly ...
But in the installer in the graphical selection section some of them are not present ...
Some months ago ( 2020 ) I did install correctly the MATE ISO though this detail did not appeared .
Any ideas ?
Impossible to say without more detail.
You can start calamares in debug mode, it will print debug in terminal and also writes it to a log file.
sudo calamares -d
gets you debug.
