Hi,
This is my first post after my introductory post here.
Just installed Endeavour (XFCE), installed pamac as well.
I tried to install Dropbox but through command line nothing really happens, through pamac I get a messsga like unable to verify signature.
I tried some guidance as I saw here on the forum, but no luck yet.
and others…
Any help highly appreciated.
Thank you.
Exactly what package were trying to install? The package dropbox from AUR installs fine for me.
https://aur.archlinux.org/packages/dropbox/
yay -S dropbox
edit:
The link you posted shows installation manually - which is perfectly ok, but EndeavourOS comes preinstalled with yay so you can just run the command above and it will do all that for you.
here are the results:
[limo@lenovo ~]$ yay -S dropbox

As far as I know it mentioned something about signature or so… in pamac it took me in loops.

Just proceed like before
n then enter
limo@lenovo ~]$ n
bash: n: command not found
[limo@lenovo ~]$
That’s strange! 
Let me restart!
Wait I think we need to pedal back a little bit.
You should check out a video or article about yay.
Type in terminal and hit enter, keep hit enter if any options given to follow through install. It will just select default option.
sudo pacman -S python-gpgme
Then
gpg --recv-keys 1C61A2656FB57B7E4DE0F4C1FC918B335044912E
If does not work then another keyserver can be used
gpg --keyserver hkp://pgp.mit.edu --recv-keys FC918B335044912E
limo@lenovo ~]$ sudo pacman -S python-gpgme

Is it OK now? Hopefully! 
Start up Dropbox and lets see 
Did they install dropbox yet?
not there yet!
Should install? pamac or command line?
