My /boot partition is nearly full and I get a warning every time I reboot my system. I already deleted old kernel packages (linux-headers...), actually I did that to install a newer kernel version that came with the automatic updates.  After installing that new version, the partition is nearly full again. So what else can I delete? Are there some other files associated to the old kernel images?  Here is a list of files that are on my /boot partition:  :~$ ls /boot/ abi-2.6.31-21-generic         lost+found abi-2.6.32-25-generic         memtest86+.bin abi-2.6.38-10-generic         memtest86+_multiboot.bin abi-2.6.38-11-generic         System.map-2.6.31-21-generic abi-2.6.38-12-generic         System.map-2.6.32-25-generic abi-2.6.38-8-generic          System.map-2.6.38-10-generic abi-3.0.0-12-generic          System.map-2.6.38-11-generic abi-3.0.0-13-generic          System.map-2.6.38-12-generic abi-3.0.0-14-generic          System.map-2.6.38-8-generic boot                          System.map-3.0.0-12-generic config-2.6.31-21-generic      System.map-3.0.0-13-generic config-2.6.32-25-generic      System.map-3.0.0-14-generic config-2.6.38-10-generic      vmcoreinfo-2.6.31-21-generic config-2.6.38-11-generic      vmcoreinfo-2.6.32-25-generic config-2.6.38-12-generic      vmcoreinfo-2.6.38-10-generic config-2.6.38-8-generic       vmcoreinfo-2.6.38-11-generic config-3.0.0-12-generic       vmcoreinfo-2.6.38-12-generic config-3.0.0-13-generic       vmcoreinfo-2.6.38-8-generic config-3.0.0-14-generic       vmcoreinfo-3.0.0-12-generic extlinux                      vmcoreinfo-3.0.0-13-generic grub                          vmcoreinfo-3.0.0-14-generic initrd.img-2.6.31-21-generic  vmlinuz-2.6.31-21-generic initrd.img-2.6.32-25-generic  vmlinuz-2.6.32-25-generic initrd.img-2.6.38-10-generic  vmlinuz-2.6.38-10-generic initrd.img-2.6.38-11-generic  vmlinuz-2.6.38-11-generic initrd.img-2.6.38-12-generic  vmlinuz-2.6.38-12-generic initrd.img-2.6.38-8-generic   vmlinuz-2.6.38-8-generic initrd.img-3.0.0-12-generic   vmlinuz-3.0.0-12-generic initrd.img-3.0.0-13-generic   vmlinuz-3.0.0-13-generic initrd.img-3.0.0-14-generic   vmlinuz-3.0.0-14-generic   Currently, I'm using the 3.0.0-14-generic kernel.

Based on some recommendations I read online, on install of a new (Ubuntu) system, I made my /boot partition separate from / and small in size (only around 50 MB). It makes sense to me that you would only need limited files in that partition, and the boot sequence only needs so much data initial data on boot so no need (or so goes my thinking) to make it much larger.   I was surprised as I started using my system and installing software was failing due to the following (or similar) issue:  gzip: stdout: No space left on device cpio: write error: Broken pipe E: mkinitramfs failure cpio 1 gzip 1 update-initramfs: failed for /boot/initrd.img-3.2.0-18-generic with 1.   I have already seen  and am planning on doing a reinstall with a larger /boot partition. My questions are:  Why does the /boot partition data get updated when I am only installing software?  obviously 50 MB is too small for my needs, so what would be a reasonable /boot partition size?  Does it even make sense to have separate boot partition? after all it could simply use all the disk space it wants in the / partition.

I was installing 32-bit Ubuntu(ubuntu-10.10-desktop-i386.iso) on VMWare workstation 7.1. During installation an error came up with the following text.  (initramfs) mount: mounting dev/loop0 on //filesystem.squashfs failed: Input/Output error Can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs   I did a memory test which was successful, but when selecting "Try Ubuntu without installing", "Install Ubuntu" or "Check disk for defects" the same error is showing up.  I download the ISO image from Ubuntu website "http://www.ubuntu.com/desktop/get-ubuntu/download". As I couldn't find the checksum data, the ISO image was verified by mounting to a virtual drive and browsing the contents.  The ISO image is mounted to a virtual drive in VMWare and not burnt to a CD.

I'm running 12.04 - I installed kubuntu to try it out and realized that with all the bloatware applications that I didn't want it anymore - I was able to uninstall the kubuntu-desktop but there are still packages left over... How can I make sure I get rid of EVERYTHING Kubuntu installed - even the kde leftovers?  Here's some of what's left when I ran sudo apt-get autoremove kde then "tab" it displayed this:     kdeaccessibility              kdepim-runtime kdeadmin   kde-runtime kde-baseapps                  kde-runtime-data   kde-baseapps-bin              kdesdk-dolphin-plugins kde-baseapps-data   kde-style-oxygen kde-config-cron               kdesudo kde-config-gtk    kdeutils kde-config-touchpad           kde-wallpapers   kdegames-card-data            kde-wallpapers-default   kdegames-card-data-extra      kde-window-manager kde-icons-mono   kde-window-manager-common kdelibs5-data                 kde-workspace   kdelibs5-plugins              kde-workspace-bin kdelibs-bin   kde-workspace-data kdemultimedia-kio-plugins   kde-workspace-data-extras kdenetwork   kde-workspace-kgreet-plugins kdenetwork-filesharing   kde-zeroconf kdepasswd                     kdf kdepim-kresources   kdm kdepimlibs-kio-plugins        kdoctools   Those are all installed by kubuntu... correct?  I just want to go back to my Ubuntu 12.04LTS with Gnome2-classic and without all the kubuntu extras.  I started it off by just removing unnecessary apps that came with kubuntu-full - then realized I didnt want the whole thing at all and uninstalled kubuntu-full but it still says I have these as well:     alex@griever:~$ sudo apt-get --purge remove kubuntu-   kubuntu-debug-installer           kubuntu-netbook-default-settings   kubuntu-default-settings          kubuntu-notification-helper   kubuntu-firefox-installer         kubuntu-web-shortcuts

I am getting a kernel panic "not syncing: VFS: unable to mount root fs on unknown-block(0,0)" with kernel 4.13.0-43 on Ubuntu 17.10. I can boot just fine with 4.13.0-41. After a successful boot using 4.13.0-41 I can get 4.13.0-43 to boot if I boot in text mode and remove the quiet and splash options. Anyone have any ideas as to what is happening? My disk drive is a 250Gb disk with one partition (I accepted the default options when I installed the system).

After downloading the package lists for wily, I see the following errors:  Unknown Multi-Arch type 'no' for package 'compiz-core' Unknown Multi-Arch type 'no' for package 'compiz-gnome' Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-max Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-min Ignoring Provides line with DepCompareOp for package python3-cffi-backend-api-max Ignoring Provides line with DepCompareOp for package python3-cffi-backend-api-min Unknown Multi-Arch type 'no' for package 'libkf5akonadisearch-bin' Ignoring Provides line with DepCompareOp for package php-psr-http-message-implementation Ignoring Provides line with DepCompareOp for package php-psr-log-implementation Ignoring Provides line with DepCompareOp for package php-math-biginteger Unknown Multi-Arch type 'no' for package 'compiz-core' Unknown Multi-Arch type 'no' for package 'compiz-gnome' Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-max Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-min Ignoring Provides line with DepCompareOp for package python3-cffi-backend-api-max Ignoring Provides line with DepCompareOp for package python3-cffi-backend-api-min Unknown Multi-Arch type 'no' for package 'libkf5akonadisearch-bin' Unknown Multi-Arch type 'no' for package 'compiz-core' Unknown Multi-Arch type 'no' for package 'compiz-gnome' Unknown Multi-Arch type 'no' for package 'compiz-core' Unknown Multi-Arch type 'no' for package 'compiz-gnome' You may want to run apt-get update to correct these problems   It then proceeds to abort the installation. The suggested run of apt-get update doesn't seem to do anything. Googling for the above error messages yielded others having similar problems when upgrading to other, previous releases, although I've not come across any apparent fixes. It's suggested that an apt upgrade could fix the problem, but I don't see a way to easily do that (it's up to date with the latest trusty package).  What should I do in order to upgrade directly to 16.04?

Still a greenee at Linux as there are so many different approaches/ways to do the same thing.  When I attempt to update to Ubuntu 17 I receive:  "The upgrade has aborted. The upgrade needs a total of 317 M free space on disk '/var'. Please free at least an additional 55.4 M of disk space on '/var'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'."  How can I safely reduce the size of this directory?

I have recently noticed these errors on startup (they occur every startup):  Jun 29 08:07:09 MATRIX kernel: [   10.773473] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun Jun 29 08:07:09 MATRIX kernel: [   10.773876] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A Jun 29 08:07:09 MATRIX kernel: [   10.773895] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun   What do they mean and what should I do about them?
