Error while trying to install something on the terminal

[gaas]

And how do i do that?

Not sure which bit of the post you are asking about.

o specificare una soluzione

Is a reference to the fact that the command that apt suggested can't resolve the problem.
That means we have to work out what is wrong and specify a solution to get apt or dpkg to correct the situation.
This is proving difficult.

You could check your cli history to see what commands were run to install.

This assumes you used the command line to install powerctl.
If you did, open a terminal by pressing 'Ctrl' Alt' and 'T' together
In the window that opens enter the command

Code:

history

followed by enter.  This will list the most recent commands entered on CLI.
Scrolling back through the list may show the command(s) used to install the powerctl software - provided you haven't used too many commands since installing or cleared the history.

I found out that after i installed "cpufrequtils" i couldn't install apps, is there a way to delete this?

this is the commands that i used :
171  apt-get install cpufrequtils
  172  apk add cpufrequtils
  173  sudo apt install cpufrequtils
then i got the error, and tried to fix it
  174  apt --fix-broken install
