Torch7: cannot download packages using luarocks

[wyvern92]

I tried luarocks in the terminal:
$ luarocks install image

but it said this:
Warning: Failed searching manifest: Failed fetching manifest for https://raw.githubusercontent.com/torch/rocks/master - Failed downloading https://raw.githubusercontent.com/torch/rocks/master/manifest
Warning: Failed searching manifest: Failed fetching manifest for https://raw.githubusercontent.com/rocks-moonscript-org/moonrocks-mirror/master - Failed downloading https://raw.githubusercontent.com/rocks-moonscript-org/moonrocks-mirror/master/manifest

Error: No results matching query were found.

How can I get rid of this problem? Thanks!

sudo rm -rf ~/.cache/luarocks

Then try again.

Hi,
Running into the same problem.
already tried the sudo rm -rf ~/.cache/luarocks and tried again.
And still get the same error. @soumith

I'm running the torch7 on a ubuntu 14.04 LTS pc behind a proxy. I have already made environment variables Http_proxy and proxy.

The default options for wget and curl and git has been set to run via this proxy. here are the steps I used to change the settings of the packages of Wget proxy, Curl proxy & git proxy

The env variables are available in my .bashrc and /etc/enviornmentfiles.

I have also added the proxy in the config.lua file as per this post as well.

The error I get when i try to install this is

$sudo luarocks install cunn
Warning: Failed searching manifest: Failed loading manifest: 
Failed fetching manifest for http://luarocks.org/repositories/rocks 
- Error fetching file: Failed downloading

I am trying to download qtlua and facing the same issue:
sudo luarocks install qtlua
Warning: Failed searching manifest: Failed fetching manifest for https://luarocks.org - Failed downloading https://luarocks.org/manifest - /home/ubuntu/.cache/luarocks/https___luarocks.org/manifest

In my case, the following code solved the problem. In ubuntu 16.04
sudo rm -rf ~/.luarocks
