Fedora 25 : Gnome Software Center and Curl not working behind proxy

Question

Update - I'm on Fedora 25 now but the issue is still unsolved.

I have Fedora 25 Workstation on my laptop. The internet access is through proxy server only.

I have successfully configured proxy settings for dnf and wget. I can install and updates packages using dnf from terminal. wget and firefox also work.

But Gnome Software Center and curl do not work. Everytime I try to install something from software center, I get the error

Curl error (7): Couldn't connect to server for https://mirrors.fedoraproject.org/metalink?repo=fedora-24&arch=x86_64 [Failed to connect to mirrors.fedoraproject.org port 443: Connection refused]

What I have tried so far:

1 : Set proxy settings using dconf-editor (Source)

2 : Manually add proxy info to /etc/PackageKit/PackageKit.conf (Source1) (Source2)

3 : Add proxy info to ~/.bash_profile, ~/.curlrc, /etc/profile (Source)

None of these have worked.

How do I get Gnome Software Center working?

Answer 1

You could try working around this by adding proxy=... after every single metalink= line in /etc/yum.repos.d/*.repo. I haven't tested this, but these are only config files which the PackageKit daemon will accept proxy settings from. Support for setting a proxy in /etc/PackageKit has been removed.

What's supposed to happen, is the PackageKit client sets a proxy. With pkcon (console command) this is based on environment variables; with GNOME Software, it is based on the GNOME proxy setting. I think neither of these work correctly at the moment though:

In a corporate environment, with proxy only web access, I configure through the GUI the HTTP, HTTPS and FTP proxy.

When I use "Software", nothing happens. I can browse the catalog, but install does not work.

If I use "pkcon" from command-line, I get an error:

[…@… ~]$ LC_ALL=C pkcon -v update
10:04:32  PackageKit          Verbose debugging enabled (on console 1)
10:04:32  PackageKit          failed to set proxy: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._pk_2dengine_2derror_2dquark.Code3: setting the proxy failed
Command failed: The proxy could not be set: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._pk_2dengine_2derror_2dquark.Code3: setting the proxy failed

"dnf" works, and the environment is correctly set.

If I unset in the shell all proxy, pkcon tries to download, but fails, obviously.

Version-Release number of selected component (if applicable): I'm using latest PackageKit on F24 : 1.1.1-3.fc24

Just updated to F25 final, still the same bug.
