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: initramfs-tools (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1512026 Title: package initramfs-tools 0.120ubuntu6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 Status in initramfs-tools package in Ubuntu: Invalid Bug description: I'm trying to install Ubuntu onto a new SSD with non-functioning Windows partitions. The Windows OS partitions were cloned from another drive using Clonezilla. I'm hoping that installing Ubuntu will write a new boot sector or something like that and make everything bootable. The whole process is in order to migrate Ubuntu and Windows from two separate SSD's in the same laptop onto a single (larger) SSD so that I can use the DVD writer again. Thanks for any help!
