Issue

Description of problem: A customer is experiencing an issue with a NTLM proxy during the ugprade. As per the strace, the connections through the NTLM proxy with credentials work with subscription-manager/RHSM, and then with yum/urlgrabber, but NOT with libdnf, the 2nd step used to get the RHEL 8 metadata. This time, we can see in a recvfrom() the proxy returned the error below: ~~~ HTTP/1.1 407 Proxy Authorization Required Date: Tue, 29 Sep 2020 10:48:59 GMT Content-Type: text/html Proxy-Connection: keep-alive Via: 1.1 COLOIG Cache-Control: no-store Content-Language: en Proxy-Authenticate: Negotiate Proxy-Authenticate: NTLM Content-Length: 666 <-cut-> ~~~ Version-Release number of selected component (if applicable): leapp-repository-0.10.0-2.el7_8.noarch libdnf-0.22.5-1.el7_6.x86_64 How reproducible: 100% for the customer Actual results: ~~~ 2020-09-25 12:56:49.864423 [ERROR] Actor: target_userspace_creator Message: Unable to install RHEL 8 userspace packages.

Error: Unable to find a match: dnf ~~~ Additional info: Sounds close to this kind of bug, fixed in Fedora 26: https://bugzilla.redhat.com/show_bug.cgi?id=1387622 Suggested the following workaround (still waiting for the feedback as I can't reproduce myself): ~~~ echo proxy_auth_method=ntlm > /etc/dnf/dnf.conf ~~~
