Recently when I was trying to update my Ubuntu, I initially used the commands:
sudo apt-get update && sudo apt-get upgrade
Then, I thought my system is full updated (i.e., with system and security updates), but gradually I found that Ubuntu was still prompting for certain updates, and those were actually the system updates. Proceeding, I read some discussions online, and started using,
sudo apt-get update && sudo apt-get full-upgrade
This also downloaded certain files like:
linux-headers-generic
linux-image-generic
etc.
Yesterday, someone suggested me to use:
sudo apt-get update && sudo apt upgrade
instead, since, it was mentioned that, apt-get full-upgrade might cause error and is dangerous, for it can lead to deletion of necessary packages if the package system is "messed-up".
Now, I am a bit confused, and feels like to start over again.
Which command set should I use to get full system and security updates, and what is the actual difference between apt-get full-upgrade and apt upgrade. Is the former shouldn't be really put to use?
