/etc/apt/sources.list and did
sudo apt-get update, and
sudo apt-get install emacs-snapshot-el emacs-snapshot-gtk emacs-snapshot to install emacs snapshot under 13.04. I obtained
failed to fetch and other errors, probably due to emacs-snapshot not being available for 13.04 (yet). I then added the above lines in
/etc/apt/sources.list also for
quantal in the hope that would work to install emacs snapshot under 13.04. Although this looks less hopeless, I obtained:
Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: emacs-snapshot : Depends: emacs-snapshot-bin-common (= 2:20130317-1~ppa1~quantal1) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
How can I solve this?
