elpa & proxy authentication

elpa & proxy authentication

[Luca Ferrari]

Hi,
I believe this is trivial but I cannot find a solution: I'm behind an
http proxy that requires authentication, and I cannot install packages
using elpa.
I've placed in my .emacs file something like:

(setq url-proxy-services '(("no_proxy" . "work\\\\.com")
			   ("http" . "<user>:<password>@<proxy>:<port>")))

and the first time I try to refresh the package list I got prompted
for the username, that is the same I specified, and for the password,
and then a generic error "unable to download package gnu" appears.
Then I try to download and install a package, I'm prompted again for
username and password for the proxy (and this time the username is the
one I'm running emacs within, not the one specified in the
configuration file) and Emacs still gives me an error that cannot
download: "Error during download request: proxy authentication
required".

Any idea?
Thanks,
Luca

Hi Luca,

You need to provide more info about your environment.

I know when I needed to do this the only solution I was able to come
up with was to use the http_proxy environment variable. Not sure why
what you did wouldn't work but all of the various tools I use,
including emacs, seem to honor the environment variable.i

I'm running emacs 24.2 on Kubuntu 12.10 64 bit.

I've tried it, but again the editor asks me for usernam/password each
time I try to do a net-related operation and then refuses to download
packages with the same error (Proxy authentication required).
Of course, I've tried using http_proxy variable and, at the same time,
I removed the .emacs configuration. Please note that the same
http_proxy variable value works from the command line (e.g., wget
something works).

Any idea?

url-auth.el uses auth-sources.el. So you could try to configure your
proxy server credentials this way. See

  (info "(auth)Help for users")

for an example how to specify passwords for http.
