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! ** Tags added: needs-new-casper ** Changed in: nvidia-graphics-drivers-173 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-173 in Ubuntu. https://bugs.launchpad.net/bugs/788589 Title: package nvidia-173 173.14.28-0ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-173/+bug/788589/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
