I create bootable sdcard with etcher and then expand my rootfs partition with gparted and there is the next problem:
System starting without GUI and also without lots of services because of read-only filesystem. I can avoid this problem with this command:
mount -o remount,rw /
But services that has not started from the boot - I can't start it. Like Wayland, Gnome, for example.
Ubuntu 20.04
