Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The version of update-initramfs that you likely have installed is unable to work on a persistent usb stick. You can resolve this issue by upgrading the version of casper on your system. This can be done via the commands:

sudo apt-get update; sudo apt-get install casper

Then performing the software update or installation that you were originally trying. If this does not resolve your bug please set its status back to New. Thanks in advance!
