I normally update my Linux Debian using the Update manager, but how can I do that using the terminal?
1 Answer
On Debian and most Debian-based distributions (including Ubuntu):
Refresh the package database:
apt update
,apt-get update
oraptitude update
Install new packages:
apt upgrade
,apt-get upgrade
, oraptitude safe-upgrade
.apt(-get) upgrade
only updates existing packages and is safer, whileapt full-upgrade
orapt-get dist-upgrade
may install new dependencies or remove existing ones.

And when do I know that a system restart is required after upgrading (let's say because of a kernel upgrade) Aug 6, 2013 at 13:31

Most update(except kernel and nvidea) won't require system restart. Because unlike Windows, open file won't prohibit the writing over it. However sometimes when running service is updated and you want to use the new version immediately, you merely need to restart that service alone(if not done by the upgrade script already).– ChongJul 16, 2015 at 5:34
