I am preparing to upgrade the machine from CentOS 7 to AlmaLinux 8. I referred to this article https://ostechnix.com/migrate-centos-7-to-almalinux-8-centos-8-rocky-linux-8/ .

I have completed the sudo leapp preupgrade step without any errors, but when I execute sudo leapp upgrade I receive the following error:

Install     476 Packages
Upgrade    1098 Packages
Remove      200 Packages
Downgrade    18 Packages

Total size: 1.7 G
Total download size: 1.6 G
DNF will only download packages, install gpg keys, and check the transaction.
Downloading Packages:

The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.

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
Warning: Package marked by Leapp to install not found in repositories metadata: python3-nss ldns-utils

How can I fix this error?

Thanks

looks like you can’t reach the mirror server, maybe something t o do with your missing dnssec package (from PowerTools repo as i recall). python3-nss will just be python-nss on alma8. maybe just remove them?

looks like similar errors as here - due to 3rd party repo’s it seems:
