some commands do not function any longer

[christon74]

Good morning fellow ubunters):P
I am the grumpy type, I know I am. I regret upgrading from 14.04 to 16.04. When I try updating _ because you are not always informed of updates_ and the updater does not function properly _ it happens that it abruptly aborts without any explanation_ I try updating using the terminal. But with 16.04 you cannot do it anymore.

christophe@hp1:~$ sudo su
[sudo] password for christophe:
root@hp1:/home/christophe# sudo aptitude update
sudo: aptitude: command not found
root@hp1:/home/christophe# sudo aptitude safe-upgrade
sudo: aptitude: command not found
root@hp1:/home/christophe# sudo aptitude full-upgrade



I have a dream that someday, someone will come up with an operating system you only need update every three months.

Have a nice Monday all of you. ;)

Phew! I have just found the answer:
Ubuntu 16.04 uses the apt package manager. To update from the terminal command line type in the following:

sudo apt update
sudo apt upgrade

But I maintain. 14.04 was better.

Aptitude does not come installed by default and it has not for a long time, I think you can still install it in 16.04 but I do not in my system I have no reason too.

sudo apt-get install aptitude
should do the trick if it is in the repo's still.

As far as I know you have to install aptitude in both trusty and xenial to use the aptitude command.
apt is supposed to be a more user friendly version of apt-get. You can still use apt-get in xenial.

The apt command is meant to be pleasant for end users and
does not need to be backward compatible like apt-get(8).
What is the difference between apt and apt-get? (http://askubuntu.com/questions/445384/what-is-the-difference-between-apt-and-apt-get)

Just throwing this in.


sudo apt update
sudo apt full-upgrade

... is more efficient than the combination you posted. See 'man apt' in a terminal for the difference. ;)

'apt' is not just a convenient abbreviation and innovation to replace 'apt-get' and aptitude. It is fully refurbished and more efficient. See here (https://www.maketecheasier.com/apt-vs-apt-get-ubuntu/) for more detail.

The author of that page seems a bit over-enthusiastic.

Perhaps. 'man apt' is a more sober account, less flowers, says what it does. ;)

One already exists. It is on your machine right now. All you have to do is change the setting to "never" and run Update Manager whenever you want to update.
