snapd does not use system proxy settings

[Noel Grandin]

I'm seeing this in the logs:

And I guess it's because I'm behind a proxy, and most things don't seem to read the system proxy settings.

This is Ubuntu18.

Perhaps the control-panel thingy should be setting the https_proxy environment variable(s)?

The control-panel thingy _used_ to set https_proxy via /etc/environment, if it doesn't that might be a bug. Or maybe you set it and didn't restart snapd? That would also have this effect.

(please set back to New after answering that)

[Noel Grandin (noelgrandin)]

I did set it, and I did restart.

This is probably the same problem that I've seen elsewhere, where snapd is being run via sudo or something similar, and sudo strips the relevant environment variables.

So really this is a system-wide design problem with the interaction of sudo and proxy settings.

No idea what the right answer is - making everything talk dbus to some config daemon to get proxy settings?

[John Lenton (chipaca)]

Sorry I was unclear: when you set the system-wide proxy, did it update /etc/environment?

[Noel Grandin (noelgrandin)]

I don't know, and I'm not using Ubuntu any more, sorry, feel free to close this.
