On doing a quick check of what update-manager can actually do, I did what I should and checked which command line options are available, and found a little usability gem (highlighted):
arve@carnage:~$ update-manager -help Usage: update-manager [options] Options: -h, --help show this help message and exit -c, --check-dist-upgrades Check if a new distribution release is available -d, --devel-release Check if upgrading to the latest devel release is possible -p, --proposed Try to run a dist-upgrade --dist-upgrade, --dist-ugprade Try to run a dist-upgrade
p. I like that. Another typo-helper is to locate the nearest shell and do sudo apt-get install sl. You’ll quickly learn to type ls correctly.
