Hi there,
I am new to it and trying to install Signal desktop on my computer. I followed the instructions on the signal.org website, but it appears that the gpg command does not exist. I don’t get it.
Do you know what I did wrong, or what I can do to fix it?
Thanks a lot
Hi there, welcome to the forum. 
Please post your garuda-inxi as requested by the template.
Do not try to install applications from the internet on Archbased Linux distributions. Signal is in the repos, install it with:
sudo pacman -S signal-desktop
Hi, and thanks for your answer!
I tried and type your command, but it says “option not valid”.
I hope this is the good thing, here is the garuda-inxi copied and pasted. Is it right?

Which command results in
?
Thats right.
Just to be sure… you are trying to run the command in XFCE’s terminal, right? (also the command requires sudo, so you will need your password entered to proceed). Double check that the command is 100% the same (copy it if needed) and make sure there are no spaces before the command. (make sure there isn’t any extra spaces anywhere)
There is another hint without sudo.
LANG=C pacman -S signal-desktop
error: you cannot perform this operation unless you are root.
Maybe it need an update before
upd -- signal-desktop
Perhaps you have used a lower-cased “s” by mistake–it should be a capital “S”, like this:
I didn’t know they were several terminals. Why so?
I used the XFCE’s terminal as you said, updated it like SGS advised, then retried the sudo pacman command and there we go, Signal desktop is on me computer now.
Thanks a lot!
Where Kayo post about other terminals?
I am sure you did not.
This one
is a “one liner”, it updates your system and install signal.
Just for your information.
Haha okay, Hahaha okay then, I may have given your one liner and again the sudo command 
Well I typesearched XFCE, then all of this. I don’t know which one of the XFCE’s terminal or your command did the job, I am a bit lost here, but I guess the good thing is that now I’m good with it!
Thanks for the info 
Last hint today, the name of this terminal is
xfce4-terminal
I hope we have only a language translation problem about your sudo command.
Did you mean the question about the root password?
Just try again for fun
upd -- signal-desktop
then you type your password.
Did not use the Enter key!
You got this
warning: signal-desktop-7.50.0-1 is up to date -- reinstalling
Well I didn’t have to type my password for any of the above.
I will keep the hint about the terminal in mind, thanks.
