Actually the way it behaves- first it flashes that top line, "/dev/sd3 clean", then goes to the purple screen, then goes back to terminal and prints the prompt under it that line.

I have one more idea
boot the live iso, mount /dev/sda3 to /mnt and sda1 to /mnt/boot/efi
run the mount --bind commands and chroot into the system, edit your /etc/resolv.conf so you don't get resolve error.
run
apt-get update

colorpurple21859 · 02-08-2020, 06:35 PM

what happens if you type systemctl default

Rotwang2 · 02-08-2020, 06:40 PM

Woa! systemctl default makes the screen go black and flash lines of text all over and then the session dies!

Ok did you mean to try that after I bind and chroot?

colorpurple21859 · 02-08-2020, 06:41 PM

at the emergency prompt login and run

Code:

dmesg |less

post the last several lines of code.
and

Code:

journalctl -xb

Ok I'll go back in and try the dmesg |less thing. Anything else before I go back in?

Oh you want journalctl -xb I just noticed your edit. it's 60 pages long- I've got an idea- since I'll be root I can write the output to disk rather than take some stupid screencaps, right? So:

dmesg > /dout.txt
journalctl -xb > /jout.txt

Right?

well if that won't work I can journalcrtl -xb | tail -50

Rotwang2 · 02-08-2020, 07:10 PM

well anyway here I go

colorpurple21859 · 02-08-2020, 07:23 PM

in the chroot what happens if you run apt-get upgrade

colorpurple21859 · 02-08-2020, 07:25 PM

I have a feeling this has something to do with how systemd mounts things, which I'm not very familiar with yet.

Rotwang2 · 02-08-2020, 07:32 PM

http://onehammer.com/jo.txt

http://onehammer.com/dm.txt

and systemctl default had the same behavior as exit.

colorpurple21859 · 02-08-2020, 07:42 PM

There is something wrong with the home partition filesystem

Code:

It was working fine in the old install. Everything was until I tried to reinstall python.

Also I can see it and change it fine here in live iso.

Do you want me to run SMART tests on the drive?

Actually even if the home partition was a little corrupt that wouldn't stop boot right?

Not according to the journalctl ouput. Boot the live iso and open a terminal

Code:

fsck /dev/sda2
