This is a very old bug.  Why don't you file a new report and explain the steps you are using and what you are seeing.  You can reference this bug as possibly being related.

I'm using 5.1.0-w64 and I also have this issue. Re-open or new issue?

Version 4.4.0 is deprecated and no longer supported.  Please try with the latest stable release which is 5.1.0.  The problem is likely to have been fixed.

You can put the command to set the proxy server in to your .octaverc file which is executed at startup.  At least that way you won't have to type it in every time.

For the Community News, I don't see what more can be done.  For whatever reason, the combination of operating system, network settings, and Octave cannot be made to work.  On the positive side, there is not much reported on Community News besides the release of new versions.

pkg -forge list

works with IP address, and also with the URL of the proxy server.
(But I need to set the proxy by the putenv/setenv command at every restart of Octave, as I wrote below.)
News/Community News does not ("Octave's community news source seems to be unavailable."), even if I use the menus.

This may not be resolvable.  The finaly thing to try would be to use the URL, rather than the IP address of it, in the environment variable https_proxy.

The code should be

setenv ('https_proxy', 'https://THE_URL_OF_YOUR_PROXY:PORT_NUMBER')

For example, if the proxy was called "proxy_A" and the port was 5000 then the full command would be

setenv ('https_proxy', 'https://proxy_A:5000')

To test, start with

pkg -forge list

If that starts to return data then you can interrupt it with Ctrl+C.  The next step would be to use the menus and try News/Community News and see if it returns anything.

Manual proxy configuration works in Firefox and Chrome also. I can reach both




Remark, that I use the URL of the proxy server instead of the IP address of it. I have just figured out, that Chrome truncates automatically the "http://" part of the given URL, while Firefox does not, and it works only if I leave out this part of the URL.
I checked in Octave also, whether it helps if I include or not the "http://" part, but it does not matter. Community news does not work inside Octave.

It's possible that your proxy is filtering out results.  If you use a regular web browser, and configure https proxy manually to be port 8080, can you reach


What about

I have tried without the slash, with setenv and putenv also, but the Community News could not load in.

The proxy set in Edit/Preferences/Network in the GUI does not seem to be used which is a bug.

Can you try starting a new session of Octave and immediately executing

setenv ('https_proxy', '')

and then using the menu for News/Community News?

Note that the change from your previous code in comment #4 was to drop the slash '/' at the end of the proxy.  I don't think that is a valid character.

I have installed Octave 4.4.0 and the issue is modified, but still exists. After executing

 putenv ('https_proxy', '');

I could execute

 pkg install -forge symbolic

but the Octave community news does not work in any way.
I have "Use proxy server" checked, HttpProxy chosen and the hostname and port filled at Edit/Preferences/Network after executing the above putenv command.
However, after Octave restart, Edit/Preferences/Network settings remains the same, but I need to reexecute the putenv command to get network connection.

Version 4.2.1 of Octave is deprecated.  Could you download the latest stable version 4.4.0 and try to replicate the issue?

Otherwise we can close this report as being on an unsupported version.

Mike, I have tried what you had suggested, and it does not help.

Thanks for the bug report. I don't have access to Windows or to a proxy set up to test with, but can you try setting "https_proxy" instead of "http_proxy"? Octave Forge packages are installed over HTTPS, and the library used by Octave uses distinct environment variables for each protocol.

I am using Octave 4.2.1 configured for "x86_64-w64-mingw32" at Windows 10, and behind a proxy server. I cannot connect the package manager nor Octave Community News, however I set the proxy server (hostname URL) and port as my system administrator suggested. I have set these settings in the GUI at Edit/Preferences/Network, and also tried from the Octave command line with

putenv ('http_proxy', '');
putenv('http_port', '8080');


putenv ('http_proxy', 'http://something.myinstitute.org:8080');

as suggested at

I still get
"error: get_forge_pkg: could not read URL, please verify internet connection
error: called from
    get_forge_pkg at line 66 column 7
    get_forge_download at line 26 column 12
    pkg at line 382 column 29"

pkg install -forge symbolic

for example.

(I hope I post this in the right category, this is my first bug report at this site.)
