Some el7 packages ware not uninstalled.

[kfujina]

I tried the migration from CentOS 7.9 to AlmaLinux 8.4 on XenServer 7.X, and it was successful.

But following el7 packages ware not uninstalled.

[root@test-cent79-tpl ~]# rpm -qa | grep el7

I wish these packages are deleted automatically or by one command.

I have similar issue from C7toRL8. let me know if I need to create a separate issue.

[kfujina]

I think you don't need to separate a issue.

@tjyang I see a lot of "external" packages in your list. I mean not from CentOS main repos.
Currently leapp doesn't support extra repos. We have to implement such support in ELevate project and try to contribute upstream.

@kfujina yes some packages can stay. I think we can remove some of them automatically like "btrfs-progs". But for old kernels and leapp itself it can be harder.

FWIW, Red Hat documentation explains why the leapp packages remain post-upgrade, and what cleanup steps should be done:
