Burada cesitli olaylar olacak oncelikle sirayla bunlari yapalim

sudo rmmod pata_acpi
echo PermitRootLogin yes | sudo tee -a /etc/ssh/sshd_config
sudo leapp answer --section remove_pam_pkcs11_module_check.confirm=True

sonra kernel devel cok var dedi eski kernelleri silelim

yum install yum-utils
package-cleanup --oldkernels --count=1

sonra gene hata verdi bir sunucuda vermemesi gerekirdi
bunlari yaptim

 Title: Leapp detected loaded kernel drivers which have been removed in RHEL 8. Upgrade cannot proceed. Summary: Support for the following RHEL 7 device drivers has been removed in RHEL 8:

lsmod | grep -q pata_acpi && rmmod pata_acpi
lsmod | grep -q floppy && rmmod floppy

sonra python3 eyvah dedi

alternatives - set python /usr/bin/python3

ya da buda olabilir ki oldu
