[SOLVED] How to uninstall old build before installing most recent one

I discovered the Linux build in the block post from about a year ago and assumed the link in that blog post would be for the most recent build. It doesn't work for me, saying that the "service is unavailable" on my Ubuntu 16.04.1 machine. I figured I'd try the most recent build after reading this forum and seeing that the most recent build is actually (as of right now) from the September 27th. Is there any special process I should do to uninstall the old build first or is it safe to just run the .deb file for the most recent build?

 

I think I solved my issue myself. I gave it a go and just installed the latest one. It overwrote the old one cleanly as far as I can tell. There aren't any repeated icons in the launcher, just one for Unity and one for MonoDevelop. Unity launches properly now too, no more "service is unavailable" error message. MonoDevelop didn't launch at all until I installed the "mono-complete" package, and even now it has a warning as I launch it saying "The following add-ins could not be started: MonoDevelop.GnomePlatform,5.9", but it does launch after displaying that warning and seems to work fine.

I'll leave this thread up in case anybody has any input or has the same question in the future.

 

If you want to uninstall it, you can remove the unity-editor package (sudo apt-get remove unity-editor if you're using Ubuntu). I don't know if same applies to the .sh installer or not.
