Hi,

you can run this command without being able to start your install? How
are you doing this? I would expect you need to read the journal by e.g.
running a live Linux using the "strings"-command. What does the journal
tell word-for-word?

How is it mounted? By fstab? By UUID? Have you checked that the
partition is still sdb5? It did not become e.g. sdc5?

From where did you try it? A live Linux? What is the reason for the
alternative superblock option? What output do you get?

One guess is, that your install expects that sdb5 is tmp and while sdb5
does exist, it's perhaps a file system that can't be accessed for tmp
usage. It might be that tmp is mounted by fstab using sdb5 for it's
entry, instead of using an UUID. However, it's not granted that tmp
is always sdb5, it might become sdc5, just because an USB stick is
connected. IOW you might need to mount tmp by UUID or even better,
unless you are low on memory mount tmp as tmpfs either by fstab or by
systemctl.
