Internal Server error while accessing Autoinstallation profiles in SMLM WebUI

SUSE Multi Linux Manager 5.x

After migration from SUSE Manager 4.3 to SUSE Multi Linux Manager 5.x,  clicking Autoinstallation Profiles results in an Internal Server Error in  the WebUI.

The following is  logged in the rhn.webui.log:

Each *.json file of the profile need to be verified and the files with an incorrect path for the distribution must be replaced with the correct one.

The files where the distribution path is correct can be ignored.

Get the list of profiles and the distributions:

ls -l  /var/lib/cobbler/collections/distros/
ls -l /srv/www/distributions/

Example :

Edit the distro file sles15sp5-suse-base:1:JLR.json :

change the wrong path

initrd "/srv/www/htdocs/distros/SLES-15-SP5-DVD-x86_64/boot/x86_64/loader/initrd" 
kernel "/srv/www/htdocs/distros/SLES-15-SP5-DVD-x86_64/boot/x86_64/loader/linux" 

to

initrd "/srv/www/distributions/1-sles15sp5-base/boot/x86_64/loader/initrd" 
kernel "/srv/www/distributions/1-sles15sp5-base/boot/x86_64/loader/linux"

Follow the same procedure for all the distribution files and then restart the cobbler service:

systemctl restart cobblerd

The profiles are corrupted during the migration from SUSE Manager 4.3 to any version less than SUSE Multi Linux Manager 5.0.5.
