The screenfetch script has the following part: https://github.com/KittyKatt/screenFetch/blob/7b8774cc31a61972b38d39958fcbda39bce4d2f5/screenfetch-dev#L1482-L1488

But it doesn't take one situation into account that snapd is not running in background, for me, snap list will take forever (more than 2mins), I got screenfetch result only after 2mins.

It should check if snapd is running in the background first, then execute the snap command and get its pkgs info.

But I googled it for a while and failed, I don't know how to check if snapd is running in the background in a cross-linux-distro way. So I'll let the developer of screenfetch do this.
