Important: do not use this PPA if you use Linux Mint or if you use the Cinnamon desktop in Ubuntu! Also, if you've added any Cinnamon PPAs, you'll have to purge them before using this Nemo PPA.
To add the Nemo 3 PPA (new PPA; the old WebUpd8 Nemo PPA still has Nemo 2.8.x!) and install Nemo with Unity patches and without Cinnamon dependencies, use the following commands:
sudo add-apt-repository ppa:webupd8team/nemo3sudo apt updatesudo apt install nemoTo install Nemo extensions, you can either search for "nemo" in Synaptic, or install them via command line - you can find the available extensions HERE.
To set Nemo as the default file manager (including setting Nemo to manage the desktop), use the following commands:
gsettings set org.gnome.desktop.background show-desktop-icons falsexdg-mime default nemo.desktop inode/directory application/x-gnome-saved-search(the first command above disables Nautilus from handling the desktop, and the second command sets Nemo as the default app to open directories)
Then restart the session (logout/login) and you're done!
To revert the changes, use Nautilus to draw the desktop instead of Nemo:
gsettings set org.gnome.desktop.background show-desktop-icons trueAnd set Nautilus back as the default file manager:
xdg-mime default nautilus.desktop inode/directory application/x-gnome-saved-searchTo remove the PPA and all the Nemo packages (including the Nemo extensions), use:
sudo apt remove nemo nemo-*sudo rm /etc/apt/sources.list.d/webupd8team-nemo-*.list
