Can't use L5 after update!

After connecting your Librem 5 over Jumpdrive again, you’ll need to trust me on this post (explaining anything in writing isn’t field I familiar with and would take too long anyway, with too many grammatical mistakes), therefore:
sudo fdisk -l
sudo umount /dev/sdb1
sudo mount /dev/sdb1 /mnt
cd /mnt

Now please post your output within this thread with:
ls -lh

I’m expecting you to list/see following files:

If no other proposal here, I expect that you might free just about enough space by (should do to power/log on into your phone):
sudo rm initrd.img −− will free cca. 62 MiB within your Librem 5 /boot partition.
sudo rm vmlinuz
sudo apt update −− if PureOS in use.
sudo apt install rename
sudo rename initrd.img.bak initrd.img −− not tested by myself, still hope this works for you (or something similar).
sudo rename vmlinuz.bak vmlinuz

As mentioned already, before disconnecting your Librem 5 from USB Type-C cable you’ll need to:
cd /
umount /dev/sdb1
umount /dev/sdb2 −− actually not sure as it is encrypted and I cannot see through my crystal … time to take your Librem 5 battery out.

@Marts, keep us informed, please. Also hope this time no mistakes from my side.
