Installing skype (12.04)
http://www.skype.com/en/download-skype/skype-for-computer/ (will autodetect you're using Linux)
Download the .deb package, open it and Software Centre should automatically open and attempt to install it.
Keyboard Testing (in browser)
http://random.xem.us/rollover.html (a little buggy with Menu key)
Another better way is to not use the browser, but instead use the showkey command in the text screen (push CTRL+ALT+F1 to access; push CTRL+ALT+F7 to return to the GUI).
Missing packages "" error
In terminal, enter:
After, running the following can help, but isn't necessary:
sudo apt-get install -f && sudo apt-get update && sudo apt-get upgrade
Fixing a full or nearly full /boot
When the /boot partition becomes very full package upgrades or uninstalls may fail due to a lack of working space on /boot. A full /boot is generally due to old kernels remaining installed, removing them is the best solution but may fail due to a lack of space on /boot. To fix this we can temporarily use space on the root partition to work with and then copy those changes back to the /boot partition.
# Make a copy of /boot on the root partition sudo mkdir /mnt/boot sudo rsync -a /boot/ /mnt/boot # Unmount the existing boot partition and # replace it with our copy sudo umount /boot sudo mount --bind /mnt/boot /boot # Perform your maintenance here # Example: remove all kernels which aren't # the currently running one dpkg -l 'linux-*' | \ sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | \ xargs sudo apt-get -y purge # Remount the /boot partition and synchronize it # with the copy sudo umount /boot sudo mount /boot # Mounts the default /boot device sudo rsync -a --delete /mnt/boot/ /boot # Clean up sudo rm -r /mnt/boot
This code doesn't work so well, unfortunately
