OK, that’s quite hard to read but lots of services are failing to start. Based on your earlier messages I believe you see the same thing whichever version of Endless OS you select in the GRUB boot menu – is that correct?
It’s hard to know for sure but this looks like disk corruption. You could try to get more information as follows:
- Press Ctrl+Alt+F3 to switch to a text-mode login prompt
- Enter your username (it’s normally your first name, in lower-case; so for me, “Will Thompson”, it’s
will
) and press Enter
- Enter your password and press Enter
- Run one of the commands suggested on that screen, such as
systemctl status upower.service
, and take a photograph of the output. Or run journalctl -b
, use Page Down to scroll to the end, and take photographs of the last few pages.
- When you’re done, run
systemctl poweroff
to switch off the computer.
Another option is to create a bootable USB disk on another computer, boot this computer from the USB stick, and then you may be able to check the built-in disk for errors using the Disks app, and/or recover your data from the built-in disk by copying it to a USB stick. https://support.endlessos.org/en/installation
