This can be reproduced when creating a bootable USB pen drive image using Ubuntu package UNetbootin. Tested with latest Ubuntu Precise Beta2 i386 desktop CD image.
However, I am not sure if this is possibly a bug of Ubuntu package "unetbootin" instead of "initramfs-tools". It is a severe problem when using an Ubuntu live-disk as a rescue system for systems using Linux logical volume management (lvm), as I had to find out the hard way. Steps to reproduce: 1. Create a bootable USB installation, using "unetbootin", of abovementioned Ubuntu Precise Pangolin Beta2 CD image, setting the persistend storage file size to a nonzero value, e.g. 3GB for a 4GB USB drive. 2. Boot from the freshly created USB drive installation and start a root terminal. 3. Install some package that triggers the update-initramfs trigger; e.g.: apt-get update && apt-get install lvm2 4. dpkg fails with "lzma: (stdout): Write error: No space left on device". Now the package management is in an inconsistent, broken state. No further package updates/removals are possible. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/926916 Title: package initramfs-tools 0.99ubuntu9 [modified: usr/sbin/update- initramfs] 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/initramfs-tools/+bug/926916/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
