one word for update

 

arguments to update either self or everything

You don't understand what update actually does and does not.

It does not install or update any packages, that's why it does not require any arguments.

Actually, you can execute apt-get upgrade <package_name> without calling apt-get update before and install a package. Here is your one word.

 

 

didn't worked for me this way

 

and the line i posted in OP i found in a tutorial:

 

https://www.3cx.com/blog/voip-howto/os-security-updates-debian/#:~:text=To%20update%20a%20single%20package,name%20we%20want%20to%20update.&text=Press%20%E2%80%9Cspace%E2%80%9D%20to%20scroll%20through,apt%2Dget%20upgrade%20packagename%20command.

 

so i assumed apt-get is just retarded

I'm 98% sure you did something wrong. Have you had somehow older version installed and then tried to install something newer?

 

That's true, but it also applies to any other package manager which based on apt lib. So you won't find anything better most likely.

 

yes, i tried to upgrade openjdk, but apt-get threw "package not found" exception, despite the package was definitely installed

 

this is why i started to think that apt-get (or whatever is in under the hood) is retarded

 

 

that Ubuntu machine is not mine

on my machine i use pacman

pacman options are less intuitive i'd say, but way easier to memorize IMO
