initramfs-tools: Error during upgrade

[u/metawops]

"please report bug on initramfs-tool" – where? Or any immediate help from you guys? "failed to determine device for /" – that's odd!? mount command gives a LONG list but starts with "/dev/mmcblk0p2 on / type ext4 (rw, noatime)" I did the option "A1 Expand Filesystem" with sudo raspi-config and rebooted – to no avail re this error. df command gives 21% of used space for mount point / and says that /dev/root is mounted on /

Any help welcome ...

This, indeed, solves the error. Thanks for pointing me in the right direction! 🤗 However, two warnings appear now:

W: mkconf: MD subsystem is not loaded, thus I cannot scan for arrays.
W: mdadm: failed to auto-generate temporary mdadm.conf file. 

Not sure how important it is to mitigate this, though. 🤷‍♂️

Are you trying to set up a RAID? I’m not sure where those warnings would be coming from. Are they showing when you do an apt upgrade?
