I'm fairly new to Linux. I have Ubuntu, and now I want to install the Pantheon desktop, but as soon I run the command

sudo add-apt-repository ppa:elementary-os/daily

I get an error message saying:

gpg: keyserver receive failed: No keyserver available

I have tried looking up a solution to the problem online, but I couldn't find any solution that worked for me. How do I solve this problem?

  • Do you have any firewall set? In such case, momentarily disable the firewall and try to add the PPA again

  • @M.Becerra I disabled the firewall, but it didn't solve the problem

  • Are you behind a (transparent) HTTP proxy server? Could you please edit your question to include the output of LC_MESSAGES=POSIX gpg --batch --no-tty --keyserver keyserver.ubuntu.com --search-keys 0x6C8769CEDC20F5E66C3B7D37BF36996C4E1F8A59 and LC_MESSAGES=POSIX wget -O /dev/null 'http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0xBF36996C4E1F8A59'? Thanks. Aug 16, 2017 at 14:57

Try the manual way,

  1. Open terminal and open sources list:

    sudo gedit /etc/apt/sources.list
    
  2. Add the lines: Look your ubuntu version and change zesty to yours.

    deb http://ppa.launchpad.net/elementary-os/daily/ubuntu zesty main 
    deb-src http://ppa.launchpad.net/elementary-os/daily/ubuntu zesty main
    
  3. Add key:

     sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4E1F8A59
    
  4. Run command:

    sudo apt-get update
    

Now you can install packages from this repo.

This is a template to add any repository from ppa.

  • add-apt-repository has --keyserver option, too.

I experienced the same issue. I am not behind a firewall, but need to use a HTTP proxy. It seems gpg does not honour these settings, at least not when invoked through add-apt-repository. So, the solution for me was to get on a network without need for a proxy; of course, that may not be possible for everybody.
