Trivial reproducer:

echo HTTP_PROXY=http://foouser:barpassword@proxyurl:8080 >> /etc/environment
sos report -o system --batch --build

I am not sure if whole /etc/sysconfig or /etc/default needs such scrubbing - various services can define the proxy there so it is imho better to cover all. BUT if either directory is password-less every time, I am happy to remove it from the postproc.

Congratulations! One of the builds has completed. :champagne:

You can install the built RPMs by following these steps:

• sudo yum install -y dnf-plugins-core on RHEL 8
• sudo dnf install -y dnf-plugins-core on Fedora
• dnf copr enable packit/sosreport-sos-3789
• And now you can install the packages.

Please note that the RPMs should be used only in a testing environment.

OK, the /etc/sysconfig or /etc/default could also collect the env.variables, worth processing them as well.

The pylint failure is solved already but checking out this pr doesn't show the commit, so I think you'll have to resync.

Good point wrt Apt plugin where I in fact copied the RE from - I just updated the PR accordingly.
