I can’t login any more after I update and reboot.
It looks like you can get to TTY now which is good, but I will leave the boot guide just in case.
Now please provide more information.
I can’t log in, so I am not able to connect to internet to paste tty out put into pastebin, is there any way ?
Likely you can use nmcli to manage your connection.
Hi, now I did boot into live manjaro evn,
I try manjaro-chroot -a
But it’s saying can’t find a grub drive for /dev/sdb1
Your chroot did succeeded.
At least it looks like that to me.
The errors are just telling you that no /dev/sdbx exists - which is true.
Your device is /dev/nvme0n1p2

Hello @quakestring 
First thing I would do is disabling the service, which failed here somehow.
- Boot Live ISO
- Chroot like you have done before.
- Run:
systemctl disable nmbd.service
systemctl disable smbd.service exit
Then you should at least be able to start a normal session after reboot.
Then investigations are needed what exactly failed here.
