Can't install on Ubuntu 16.10

If you can't see the image, it's a gdebi-gtk error dialog which says:

[ 'unity-editor-5.5.0b5+20160927_amd64.deb' is not a Debian package.

The MIME of this file type is 'application/x-debian-package' and can not be installed on this system. ]

Besides from my system having Ubuntu-MATE 16.10 (Yakkety Yak) installed, I can provide no further info.

I'm trying to install the latest release of Unity Editor but am finding trouble trying to install it. I've tried using the GDebi Package Installer, but it kept giving me the error you read above. I've also tried sudo dpkg -i unity-editor-5.5.0b5+20160927_amd64.deb but it only give me errors as well:

Any idea how I can get through this?

 

Same problem with me. Couldn't get installed

 

It looks like you might have a corrupted download - does the sha1sum match?

 

The same with me
Not first time trying

It always asks for libpng12-0 package. I am not sure where I can get it

 

Ubuntu 16.10 yakkety uses newer version of libpng (libpng16-16)
Until this is resolved by the Unity Linux Team you can always get libpng12-0 from here (it's removed from the Ubuntu 16.10 repositories)

 

Same here, it's not only libpng

The following packages have unmet dependencies:
unity-editor : Depends: libpng12-0 but it is not installable
Recommends: ffmpeg or
libav-tools but it is not going to be installed
Recommends: java6-runtime
Recommends: monodevelop but it is not going to be installed
Recommends: java7-jdk but it is not installable​

It could be nice if they can provide a Snap or Flatpack package instead since all the dependencies are self contained.

http://flatpak.org/

 

To be fair I am just glad they have a Linux version of the editor, I can handle a few dependencies. After install libpng12-0 above the install works fine on 16.10.

I needed these as well I believe: sudo apt-get install lib32stdc++6 libpq5 npm

 

Hi,

I instaled Unity 5.5.0f3 on my ubuntu 16.10 perfectly, but when i create the projects they complain about missing .net assembly and I can't compile the project. Anyone knows how I can solve it?

 

Mine has a lot of dependencies, but if i run "sudo apt-get -f install" or "sudo apt --fix-broken install" it just removes unity-editor. Here's the results i got after installing it.

I'm running this on kali linux so it might be a bit different

 

I just tried installing 5.6.0b6 (downloaded via torrents) on a fresh install of Ubuntu 16.10 x64, and it worked flawlessly. No dependency issues. No grey welcome screen. Things are working great! I used the .deb from the download and installed through Ubuntu Software.

 

Thank you for posting this. I'm about to give 5.6.0b8 a try as you have described. Link for anyone else who has issues with the "official" version that was posted: http://files.unity3d.com/levi/unity-editor-5.6.0b8+20170214.torrent

 

It works!

I had to do a few extra steps because I already had the official version installed.

1. Remove official version (sudo dpkg --purge unity-editor)
2. Manually remove the directories Unity creates under /home/name/.local/share/unity3d and another under /opt/ (sudo rm -r FolderNameHere)
3. Installed the beta version 5.6.0b8 by double clicking and letting Ubuntu Software run

Thanks again @Jesse_DuBord!
