Can't install ros-lunar on Ubuntu 16.10
I'm trying to install ros-lunar on Ubuntu 16.10 (I already tried to install it also on 17.10 with no success)
i always get this error:
sudo apt-get install ros-lunar-desktop
Reading package lists... Done

I already tried to setup my sources.list as explained in the ros-lunar installation guide. I had the same issue on Ubuntu 17.10.
When I try to run sudo apt-get update, I get errors like these ones:

How can I install ros-lunar? Can you help me, please?
Just an observation, but Lunar is not supported on
17.10, see REP-3.And note also that
16.10is EOL: notice.Please show us the contents of
/etc/apt/sources.list.d/ros-latest.liston your machine?I had the same problem on Ubuntu 17.04. Anyway, I'm using UBUNTU 16.10, not Ubuntu 17.10.
This is the output on my machine 16.10.
See Ubuntu 16.10 Update problem for why your
apt-get updateisn't working. Ubuntu Yakkety is end-of-life (ie: not supported any more by Canonical). This could be why the ROS pkgs aren't installing (as required pkgs can't be found).I'm not saying you're running
17.10now, just trying to provide an explanation for why you can't install Lunar on17.10, which you stated you were trying before.So i need to downgrade to 16.04 in order to run ROS Lunar?
The only supported (by Canonical) Ubuntu release that supports ROS Lunar would be
16.04(orXenial), yes. If you require a newer version of Ubuntu (because of hw support fi), then installing18.04and ROS Melodic would perhaps be an option.
