My Question or Issue:

 I cant install Spotify.

This is what i have tested so far and the results:


Searched for it on Ubuntu Software (app).

Can't find it.

Went to  this page "https://www.spotify.com/se/download/linux/" and clicked on this link "Spotify in Ubuntu Software".

Ubuntu Software start and i get this message: "Don't know how to handle 'snap://spotify/'


Then i tried installing it throug Terminal. I used this command lines:

"sudo snap install spotify"

This is the result i get:

"error: snap "spotify" is not available on stable for this architecture (i386)
but exists on other architectures (amd64)."

 

Then i tried install Spotify Using Ubuntu Package Manager. I used this command lines:

 

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 0DF731E45CE24F27EEEB1450EFDC8610341D9410

 

This is the result i get:

echo deb http://repository.spotify.com stable non-free | sudo tee /etc/apt/sources.list.d/spotify.list

 

This is the result i get:

Then i used this line:

sudo apt-get update -y

All you need to do is run:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys [the 16-digit key that comes after the "NO_PUBKEY" error]

Example (going off your error code):

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys A87FF9DF48BF1C90

 Then update:

Sudo apt-get update

Finally, try to install the spotify client:

Sudo apt-get install spotify-client

I hope this has helped you
