Closed this issue · 2 comments

I have a problem with Upgrade Centos 7.9 to Centos-stream 8 via proxy serwer.
I set proxy in yum,conf any dnf.conf and I set LEAPP_PROXY_HOST=

But i have a below problem, after : leapp upgrade

STDERR:
No matches found for the following disable plugin patterns: subscription-manager
Repository extras is listed more than once in the configuration
Repository extras-source is listed more than once in the configuration

How can I resolve this problem ?

@smurdza Hello, thank you for reaching out. Please note that Leapp itself is a framework that enables you to define a workflow which will, consequently, help you to upgrade or modernize your system. However defining and implementing the workflow is up to the user.

You can take a look here for inspiration:

https://github.com/oamg/leapp-repository/tree/master/repos/system_upgrade

The above is the repository containing workflow to upgrade RHEL systems (supported by Red Hat). Unfortunately, I am not aware of any supported way to get from CentOS to CentOS Stream. One can convert from CentOS 7 to RHEL 7 and subsequently upgrade to RHEL 8 in a supported way though.

With your permission, I would close this issue as not a BUG.

Thank you for your understanding.

Ok, thank you for respond.
