Update and upgrade and (?) missing files

[gonzalo-vc]

Hi, all. I prefer to update/upgrade my *buntu machines using the proper system application (updater). But sometimes I go to the terminal and do it manually, specially to use these 3 commands:
apt-get upgrade --fix-missing
apt-get autoclean
apt-get autoremove

Why is that there are, quite frequently, missing files, libraries, whatever, in ubuntu? :confused:
I think the system updating app must be upgraded to solve this.

Weekly:

sudo apt-get update
sudo apt-get dist-upgrade

Monthly:

sudo apt-get autoremove

Don't know about any GUI tools. Depending on the specific version of Ubuntu installed, might need to remove old kernels monthly too - easiest way is through synaptic, but apt-get can be used too.
