Ta, "sudo apt-get autoremove --purge" only purges automatically installed packages, but in Trusty the linux kernel packages are likely to be marked as being manually installed.
If you mean /boot/initrd.img* files by gzip archives, they should be removed automatically when you purge the respective kernel package such as linux-image-3.19.0-59-generic by dpkg (or by apt). If you have kernel junk in /boot even if dpkg does not list the kernel(s) as being installed, there may be a bug similar to Bug #1586303. You may write a separate bug report about it. If you use Trusty or later, run purge-old-kernels without sudo in shell to get to know which package to install, if the command is not found. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1357093 Title: Kernels not autoremoving, causing out of space error on LVM or Encrypted installation or on any installation, when /boot partition gets full To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1357093/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
