File a bug against those packages. They should use IDs in the system range.

If those packages are properly installed and you don't find a script for
changing uid/gids:
First, find out if there are any files or directories with the IDs:
find / -uid 501
find / -uid 502
find / -gid 501
find / -gid 502
If there are, you probably will want to chown them to whatever new ID you
pick. If they're in one place (more or lesss), use something like:
chown -R 517:517 /home501
If they're all over the place, then use a variation of the first command:
find / -uid 501 -exec chown 517:517 '{}' ';'
If you're the nervous type, do this first:
find / -uid 501 -exec echo '{}' ';'
Then edit /etc/passwd, /etc/shadow, /etc/group, and /etc/gshadow to match.
I use vipw and vigr to edit them.
