Hi knc1
Thanks so much for your detailed reply.

Sorry I missed the gui Q. Yes I do have a gui (Linux Mint / Ubuntu) however, I much prefer to do work like this with CLI in a terminal so I have a bash record of it and it reduces the chance of errors IMHO.
The logs look helpful. The checksums verified with the same MD5 as yours.
The relevant line in the log seems to be:
Code:
system: E _otaupexec:def:signature verification failed on "/tmp/.update-tmp.14149/update-filelist.dat"
The relevant section of the log is:

The MD5 of the files extracted from your archive (DevCerts) do differ from the MD5 of the ones I was originally using (Mobileread Kindlet Kit), although the problem remains the same. The filenames were identical so MD5 differences between the same? files extracted from two archives does seem strange)
Code:

Although the core information should be in this post and in particular that:
Code:
_otaupexec:def:signature verification failed on "/tmp/.update-tmp.14149/update-filelist.dat"
I will make a subsequent post with the exact steps I followed and screen shots for full information.
