Crostini not installing: Linux VM not working with latest chromeos

[suoko]

I found a way to have crostini working ok starting from older brunch+chromeos.

• Start from an older brunch+rammus, I use brunch_r90_stable_20210523.tar.gz and chromeos_13816.82.0_rammus_recovery_stable-channel_mp-v2.bin.
• Enable updates in grub
• Enable Linux (crostini)
• Install brunch toolkit
• Update brunch via brunch toolkit and update chromeos via system settings at the same time
• Reboot
• Try to login but it will probably fail
• Reboot
• Login again, this time it will be successful
• Enable Linux again, because you will find it disabled/uninstalled
