Problems with proxy on docker on Fedora 30

[soeren-b-c]

I have a clean Fedora 30 netinstall

When running
bin/make-base-vm --docker --arch amd64
I see this
Step 3/8 : RUN echo 'Acquire::http { Proxy "http://172.17.0.1:3142"; };' > /etc/apt/apt.conf.d/50cacher
followed by the error
E: Failed to fetch http://security.ubuntu.com/ubuntu/dists/xenial-security/main/binary-amd64/Packages Unable to connect to 172.17.0.1:3142:

I have a feeling it may as well be a docker problem, but I can't figure out where to go from here.

I get similar errors about failing to fetch from the proxy when trying to run with --dist debian or other --suite.

Full output:

[MarkLTZ]

Hello! I have the same issue. Did you solve it?

[soeren-b-c]

@MarkLTZ No, unfortunately I did not.

I still suspect that there is something going on with the docker networking / proxy, but I have never used docker before, so I am kinda flying blind here... :(

If you have a breakthrough, please let me know.

[MarkLTZ]

ok. for the moment I have configured it using ubuntu on Virtual Box

[abitmore]

See #228 (comment).

[soeren-b-c]

@abitmore Thanks for replying. How do you run that command on Fedora? I don't think apt-cacher-ng is included in the latest Fedora.

[abitmore]

If I'm correct, Fedora doesn't have apt, so there will be no apt-cacher-ng service on the host. I guess you need to remove the proxy settings from the code, see #66 (comment) and #66 (comment).

[devrandom]

Could also run apt-cacher-ng in a docker container - maybe https://github.com/deployable/docker-apt-cacher-ng . But I haven't tried it myself.

Pull requests to improve docs and/or disable caching would be appreciated.

[ramizpolic]

I was experiencing the same issue and managed to resolve it by restarting the apt-cacher service.

service apt-cacher-ng restart

@devrandom I'm experiencing the same output as OP when trying to setup using the gitian script with docker on Ubuntu 20.04.
