My system failed to boot this morning. It was working last night.
I used ‘space’ to get the boot menu - there are two kernel options, Clear-linux-lts2019-5.4.65-65.conf and .66-66.conf; neither work.
systemd.unit=emergency.target (to either of the kernel boot configs, 65-65 or 66-66) results in the message:
Cannot open access to console, the root account is locked. See sulog(8) man page for more details. Press Enter to continue
doing so displays the Oh no! screen.
systemd.unit=getty.target gets me a login prompt but I cannot login. My normal user account is not permitted (
"System is booting up. Unprivileged users are not permitted to log in yet. ... see pam_nologin(8)") and of course I don’t have a root password (root account is locked).
If I boot from some rescue disk, what must I do to unlock the root login, please?
Otherwise, re-installation now seems to be my best option (but will the kernel I download work?).
Any ideas on where I go from here, please?
Intel i5 on Asus Z370-P with Samsung M2 SSD root and two WD 1TB SATA disks. AMD Radeon GPU (nothing special, twin DVI, 5? years old). No encrypted filesystems.
