I have no idea ......... the first try at Solus was with 3.9999 / I got the iso around the beginning of the year.
It basically was stick the USB in the slot, turn on the computer and wait for the prompts, then click through the install process and then do a restart to a running working Solus OS.
What began as hey I will try that has morphed into - huh can't get anything Solus to do anything but give a LIVE look at the USB it will not do an install of Budgie or Mate. It gets to the point of asking for name / user name / password click for the next step after it shows what it is going to install and just stops.
Tossing up a FAILED TO LOAD screen with a Warning.
I took a pic with phone and I would post it to show what the window looks like but it will not allow me to login to forum from my phone. Linux won't let me pull the pic from my phone either .... odd ?
the install shows this
Format/dev/SolusSystem/Root as ext4 root partition
the pop reads as follows
Installation has failed, and changes were made to disk
The installer will now exit.
Failed to update disk: Partition(s) 1 , 2 on/dev/sda have been written but we have been unable
to inform the kernel of the change, probably because it/ they are in use. As a result, the old partition(s)
will remain in use. You should reboot now before making further changes.
Failed to apply disk strategy
It matters not which of the DE I use the results are the same. So I thought well I will look for an old Solus version which I found an iso for early 2017 it gave the same result. I thought well I'll see if some other distro will load, so I grabbed 2 different distros with different DE - to which both go through the install then give the restart to finish installation.
Both yielded a full working version of both installs, so I tried it again and again with Solus and still it gives the same results each time.
Now I am wondering what is it I am missing or not doing to get it to work again as it did on original install of 3.9999.
