Upgrading emacs on debian

Make sure you have the tools installed so that apt can do it's internet thing.

2

sudo apt-get install software-properties-common
sudo apt-get update

Add the signing key:

1

wget -q http://emacs.ganneff.de/apt.key -O- | sudo apt-key add

And add the packages to your local index. Note that I'm specifically using buster here so update that if you need do.

2

sudo add-apt-repository "deb http://emacs.ganneff.de/ buster main"
sudo apt-get update

I ran into a bunch of problems with the old emacs being installed at the same time, and it borked dpkg for a bit. So first lets remove everything:

1

sudo apt remove emacs-bin-common emacs-gtk

Pretty straightforward here.

2

sudo apt-get install emacs-snapshot 
sudo update-alternatives --config emacsclient

The snapshot build has a svg icon, which the Chromebook doesn't seem to like. So lets fix that up.

2

mkdir -p ~/.local/share/applications/
cp /usr/share/application/emacs-snapshot.desktop ~/.local/share/applications

And then edit ~/.local/share/applications/emacs-snapshot.desktop to put the Icon to the final image place, in my case

Icon=emacs

It took a while for the changes to take but after a reboot it works great.

Crositini will eventually update the shelf but it will take a little time.

So far, no issues and no crashes!
