My Asus Sonicmaster is in what I can only describe as the computer equivalent of a coma.

Start with archinstall/lib/disk/utils and archinstall/lib/disk/device_handler.py around unmount_all_existing, then follow the call from archinstall/lib/disk/filesystem.py. Reproduce the guided installation using the supplied log and investigate the busy /run/user/1000 unmount failure; done means the reported installation path no longer fails in this situation, with a regression check if the project supports one.

Which ISO version are you using?

describe the problem

There was an error after attempting "archinstall"

I was installing on an ASUS Sonicmaster laptop

Then I booted linux and archinstall crashed at some point during the installation ...

Everything in "installation log" was all in red.
Everything in Yellow are as follows:

Archinstall experienced the above error. If you think this is a bug, please report it to
https://github.com/archlinux/archinstall and include the log file "var.log/archinstall/install.log

Hint: To extract the log from the live ISO
curl -F 'file=@/var/log/archinstall/install.log' https://0x0.st

I will post what was in the installation log below. Hope that helps. Sorry I am an amateur at this, but I just want my laptop to get untucked plz. thanx.
