I am trying to install Emacs25 package on Ubuntu 16.04 alongside Emacs 24 and Emacs-snapshot (currently Emacs 27.0.50).
I ran the following commands
sudo add-apt-repository ppa:kelleyk/emacs sudo apt-get update
After that I ran
sudo apt install emacs25
during which I get this
user@user-desktop:$ sudo apt install emacs25 Reading package lists... Done Building dependency tree Reading state information...
