# Updating to Emacs 28 on Linux Mint

This time, using a PPA rather than building from source like last time ([[Installing Emacs from source]])

I used this for reference: [How to Install GNU Emacs on Linux Mint 21 or 20 - LinuxCapable](https://www.linuxcapable.com/how-to-install-gnu-emacs-on-linux-mint/#install-gnu-emacs-on-linux-mint-21-or-20-via-apt).

With really the main bit of info of use being which PPA to use.

```shell
sudo add-apt-repository ppa:kelleyk/emacs -y
```

I had to manually, naughtily, uninstall the old Emacs binaries from _usr/local/bin_ that had been built from source in order for the new emacs28 binaries from the PPA to be picked up.

And, of course, not it's a new version of Emacs, spacemacs has to get all the packages from MELPA again…

Got some errors while this was happening:

Which is odd, as I don't seem to have org-assert-version anywhere in my userconfig function.

Seems to be a common issue: [syl20bnr/spacemacs#15896 \`org-mode\` is broken after restarting emacs on lates…](https://github.com/syl20bnr/spacemacs/issues/15896) 

The following worked for me:

```shell
cd ~/.emacs.d/elpa/28.1/develop
rm org-9*
```

plus a restart of spacemacs.

And we're back to working again!  The org-projectile error seems to have gone.

So, [[What's new in Emacs 28?]]
