Dear Edward and Wout, thank you for your replies.
Edward, I more or less understand what your script tries to do https://github.com/edwtjo/nixin/blob/master/nixin#L103-L124. But can you advise which values for NIXPKGS_REPO are suitable? I am using a 14.04 virtualbox image for now and it does not have git installed. Wout, I have already set the http_proxy and https_proxy environmental variables (written in the very first message). Unfortunately, it is not enough, that's why this question thread. To summarize, steps taken: 1) export http_proxy=some-proxy.com:3128 --- OK 2) export https_proxy=some-proxy.com:3128 --- OK 3) export NIX_REMOTE="" --- OK 4) export NIXPKGS_REPO= --- ??? 5) rebuilding nixos --- ??? (fails because no proxy found) Thank you! 2014-11-24 17:14 GMT+01:00 Edward Tjörnhammar <[email protected]>: > On Thu, Nov 20, 2014 at 03:07:19PM +0100, masterdeZign wrote: > > Hello! > > > > I am new to NixOs, but the question which interests me seems not to be > > discussed yet. > > My workstation has access to Internet via proxy.
