To upgrade Ubuntu, please follow the steps below

sudo apt-get install update-manager-core
Then open the update-manager configuration file and make sure the Prompt line is set to lts
sudo nano /etc/update-manager/release-upgrades
Confirm that the Prompt is equal lts
# Default behavior for the release upgrader. [DEFAULT] # Default prompting behavior, valid options: # # never - Never check for a new release. # normal - Check to see if a new release is available. If more than one new # release is found, the release upgrader will attempt to upgrade to # the release that immediately succeeds the currently-running # release. # lts - Check to see if a new LTS release is available. The upgrader # will attempt to upgrade to the first LTS release available after # the currently-running one. Note that this option should not be # used if the currently-running release is not itself an LTS # release, since in that case the upgrader won't be able to # determine if a newer release is available. Prompt=lts
If not, change it to lts and save the file.

What’s going on?
Linux is borrowing unused memory for disk caching. This makes it looks like you are low on memory, but you are not! Everything is fine!
Why is it doing this?
Disk caching makes the system much faster and more responsive! There are no downsides, except for confusing newbies. It does not take memory away from applications in any way, ever!
