Description Bernie Hoefer 2019-03-15 15:37:50 UTC
Description of problem:

Customer uses an HTTP proxy for their environment.  They regularly use the "--proxy" option when executing subscription-manager commands.

Upon testing a RHEL 7.6 to RHEL8 beta leapp upgrade, they got this fatal error:


2019-03-10 19:46:27.196 INFO     PID: 30183 leapp.workflow.Download: Executing actor prepare_upgrade_transaction 
Process Process-65:

    raise CalledProcessError(retcode, cmd, output=output)
CalledProcessError: Command '['subscription-manager', 'release']' returned non-zero exit status 1


It did this because leapp has no way of knowing about the proxy.  Thus, when it runs "subscription-manager release", it exits with non-zero exit code "Errno -2".



Version-Release number of selected component (if applicable):
leapp-0.5.0-1.el7_6.noarch



How reproducible:
Try to run leapp on a machine that must use a HTTP proxy for connectivity.



Additional info:
I'm not sure whether this should really be considered a bug, or not.  Perhaps it is just something we need to make clear in the leapp documentation.

I see in "man subscription-manager" that one can set proxy values in /etc/rhsm/rhsm.conf so that one is not constantly adding the "--proxy" option to one's subscription-manager commands.  This may be the way we instruct users to handle this situation instead of programming in proxy capabilities to leapp.

Not sure about that. Assigning to Chris Snyder from RHSM team who are responsible for subscription-manager part of upgrades.

Comment 3 Vinzenz Feenstra [evilissimo] 2019-03-15 21:32:34 UTC
Bernie, is there any reason the customer cannot configure the proxy in the rhsm.conf? Or did they do that? If it would be in the RHSM conf, it shouldn't fail then AFAIK.

Comment 4 Vinzenz Feenstra [evilissimo] 2019-03-15 21:34:16 UTC
Bernie, nevermind, just noticed you added the KB. Sorry for the noise.

Comment 5 Chris Snyder 2019-04-30 15:07:36 UTC
It appears to me that this is a bug in Leapp not subscription-manager. Unless Leapp will be modified to pass a well-formed "--proxy" option to subscription-manager, the solution in the attached KB will be our only solution. My team is not responsible for any of the Leapp code, as such I'm reassigning this to the default for leapp-repository.

If you have any questions during implementation that the RHSM client tools team can help with please let me know.

Comment 10 Michal Bocek 2020-05-21 12:46:29 UTC
We have documented this issue in https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/upgrading_from_rhel_7_to_rhel_8/index:
"
If you use an HTTP proxy, Red Hat Subscription Manager must be configured to use such a proxy, or the subscription-manager command must be executed with the --proxy <hostname> option. Otherwise, an execution of the subscription-manager command fails. If you use the --proxy option instead of the configuration change, the upgrade process fails because Leapp is unable to detect the proxy. To prevent this problem from occurring, manually edit the rhsm.conf file as described in How to configure HTTP Proxy for Red Hat Subscription Management.
"

In our opinion that is sufficient. I'm closing the bug.
