Release Candidate takes precedence over final version

Summary

In raspberry pi, apt-get install prefers release candidates to final versions. For example, 10.6.0-rc7 will be installed despite 10.6.0 is the most recent release. Please, could you have a look?

Thank you for your time,

Steps to reproduce

Attempt to install/upgrade or check order using apt-cache policy as described below:

apt-update
apt-cache policy gitlab-ce

Notice that 10.6.0-rc7 is preferred to 10.6.0, 10.5.0-rc10 to 10.5.0 and so on.
