... i tried to reinstall the packages but nothing changes..

Your error seems to be the final part of the output:

E: Unable to correct problems, you have held broken packages.

You can try some of these steps: Unable to correct problems, you have held broken packages

libldap-2.4-2 is not installable in Ubuntu 22.10 because it was removed from the Ubuntu repositories after Ubuntu 20.04.

The instructions you are following are obsolete. Notify whomever you got those instructions from that they need to update it.

Alternately, you can install Ubuntu 20.04. The package is available in that release.
