I appear to have had this same issue, so I am here with a question on my twist. My daily driver is Open Suse, so it was bit of a pain getting uuu working, but I got through all that using snap and actually moving the binary file manually. So I connected fine via jumpdrive by downloading and running the script recommended by mladen et. al. All good - I have the three added drives (phone two and my SD card). However, that’s where we hit my odd twist. In the directory, neither “initrd.img” and “vmlinuz” nor their .bak’s are present:
So… I am guessing my course of action is to copy the two serialized versions to their non-serialized versions and see what happens?
i.e. cp initrd.img-5.16.0-1-librem5 initrd.img AND cp vmlinuz-5.16.0-1-librem5 vmlinuz ?
Then keep going?
