can't install ros on ubuntu?
I'm new to Linux, so I followed the install instruction, created a source list and generated key.
On updating
sudo apt-get update
Get:1 http://security.ubuntu.com/ubuntu xenial-security InRelease [102 kB]
Get:2 http://packages.ros.org/ros/ubuntu xenial InRelease [4,037 B]
Hit:3 http://in.archive.ubuntu.com/ubuntu xenial InRelease
Get:4 http://in.archive.ubuntu.com/ubuntu xenial-updates InRelease [102 kB]
Get:5 http://in.archive.ubuntu.com/ubuntu xenial-backports InRelease [102 kB]
Get:6 http://packages.ros.org/ros/ubuntu xenial/main amd64 Packages [326 kB]
Get:7 http://packages.ros.org/ros/ubuntu xenial/main i386 Packages [291 kB]
Err:7 http://packages.ros.org/ros/ubuntu xenial/main i386 Packages

I got this error. On further following the steps i ended up with

According to this question, running apt-get clean
and then running apt-get update
again may work. Deleting /var/lib/apt/lists/*
also helps, apparently.

Error: repositary http://mirror-eu.packages.ros.org/ros/ubuntu cosmic release does not contain file Release
Is it possible to download and install in another way?

That looks fine. Does
apt-get update
still give an error?Asked by Geoff on 2017-04-25 08:22:16 UTC
yes it dose. are there any alternatives to install ros.
Asked by nikhil98 on 2017-04-25 09:36:32 UTC
Yes, you can install from source. But it would take a while to compile. For the benefit of you and anyone else who has the same problem in the future, I hope we can fix the actual problem.
What does
lsb_release -a
print?Asked by Geoff on 2017-04-26 02:42:46 UTC
