How do I completely remove Unity Next?
I followed the instructions to install Unity Next. They worked, and I was able to run Unity Next.
Here are the instructions I used (quoting from the above link, with parts removed):
$ mkdir ~/unityFetch Unity Next source
$ sudo apt-get install bzr $ bzr branch lp:unity/phablet ~/unity/unity-next $ cd ~/unity/unity-nextDownload & dependencies
$ ./build -sthis will:
- Add ppa:phablet-team/desktop-deps, ppa:canonical-qt5-edgers/qt5-proper, ppa:ubuntu-sdk-team
- Build and install lp:libunity/phablet, lp:unity/phablet-mods, lp:hud/phablet and lp:unity-lens-people locally
- Install build dependencies
Build UnityNext
$ ./buildRun UnityNext
$ cd ~/unity/unity-next $ ./run
However, later when I tried to build a KDE application, I ran into a bunch of errors. The only thing that I think this could be is because of the Unity Next installation, so I would like to remove it. However, I can't find any instructions on how to remove it, either on the aforementioned page or using Google.
It appears that it installed some dependencies and a PPA, but I don't know how to easily remove them all and undo all the changes the installation did.
How do I completely remove Unity Next, including all its dependencies and extra PPAs?

Use a combination of ppa-purge and reinstallation. Disclaimer: I have not tested this in any way possibly imaginable.
Step 1: Preparation
First install the ppa-purge tool: sudo apt-get install ppa-purge or click here: ppa-purge
Step 2: Remove software
Now run:
sudo ppa-purge ppa:phablet-team/desktop-deps
sudo ppa-purge ppa:phablet-team/desktop-depsIf you're not on Raring, additionally run:
sudo ppa-purge ppa:canonical-qt5-edgers/qt5-proper
sudo ppa-purge ppa:ubuntu-sdk-team/ppaThis will remove the PPAs from your system, which basically means removing them from your software sources, and resetting the packages to the default versions from the official repos. See the manpage for the ppa-purge command for more info on how it works.
Note that while the phablet-team/desktop-deps PPA is not mentioned in the compilation guide, it is mentioned in the build script.
Next you need to remove the final binaries that you compiled. Based on your description of how you ran the software, you should be able to just run rm -rf /path/to/build/directory where /path/to/build/directory is the directory in which you built Unity Next. I think this is the directory that you would have run ./build from. If you followed the instructions without changing any paths, this directory should be ~/unity.
Step 3 (optional): remove build dependencies
Note: while these commands are written in such a way as to not uninstall any software that you don't want to be uninstalled, they will automatically remove any packages that you don't need on your system (packages installed to satisfy a dependency, but not needed anymore because nothing installed depends on them). This is a completely safe result, but be aware of what is happening.
If you want to get rid of build dependencies, and are running Raring:
sudo apt-mark auto qt-components-ubuntu qtdeclarative5-dee-plugin indicators-client indicators-client-plugin-* qtbase5-dev qtdeclarative5-dev qtdeclarative5-dev-tools qtdeclarative5-test-plugin libdee-qt5-dev libpulse-dev qtdeclarative5-xmllistmodel-plugin unity-lens-mock demo-assets libboost-regex1.49-dev ubuntu-mobile
# this next command may or may not work in Raring. let me know in a comment.
sudo apt-mark auto bamfdaemon debhelper dh-autoreconf gir1.2-dee-1.0 gnome-common gnome-doc-utils gobject-introspection gtk-doc-tools indicator-application indicator-appmenu indicator-appmenu-tools intltool libappindicator3-dev libbamf3-dev libdbusmenu-glib-dev libdbusmenu-gtk3-dev libdbusmenu-jsonloader-dev libdbustest1-dev libdee-dev libgirepository1.0-dev libgtk-3-dev libncurses5-dev libreadline-dev libsqlite3-dev metacity sqlite3 valac-0.18 libpocketsphinx-dev libsphinxbase-dev
sudo apt-get autoremoveIf you want to get rid of build dependencies, and are running Quantal or lower:
sudo apt-mark auto qtdeclarative5-ubuntu-ui-toolkit-plugin qtdeclarative5-dee-plugin indicators-client indicators-client-plugin-* qtbase5-dev qtdeclarative5-dev qtdeclarative5-dev-tools qtdeclarative5-test-plugin libdee-qt5-dev libpulse-dev qtdeclarative5-xmllistmodel-plugin unity-lens-mock demo-assets libboost-regex1.49-dev ubuntu-mobile
sudo apt-get autoremoveThe guide also has you install bzr: if you really don't want that on your system, run sudo apt-get remove bzr. It doesn't really matter though, since it's not a huge package.
