Public bug reported: "dpkg --purge" calls /etc/kernel/postinst.d/initramfs-tools when purging/removing a linux-image-extra package. That calls "update- initramfs -c" which needs significant amount of additional disk space in /boot temporarily. But there is no space left, if /boot is full.
The fix could be to create the new initrg.img file in different partition before replacing the old one by it in update-initramfs. So the update-initramfs script should be fixed. A workaround would be to remove the respective /boot/initrd.img-<version> file before running dpkg --purge for the linux-image-extra package. That could also be done by sudo update-initramfs -d -k <version> Related question: http://askubuntu.com/q/898499/21005 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: initramfs-tools 0.103ubuntu4.7 ProcVersionSignature: Ubuntu 4.4.0-71.92~14.04.1-generic 4.4.49 Uname: Linux 4.4.0-71-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.23 Architecture: amd64 CurrentDesktop: XFCE Date: Fri Mar 31 17:42:35 2017 EcryptfsInUse: Yes InstallationDate: Installed on 2014-09-21 (922 days ago) InstallationMedia: Ubuntu-Studio 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.1) PackageArchitecture: all SourcePackage: initramfs-tools UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: initramfs-tools (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1678187 Title: update-initramfs requires more space in /boot when removing a linux- image-extra package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1678187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
