I'm stuck with the upgrade.
After trying upgrade-edgelinux script, it gets stuck on the emerge
How do I move forward?
* Last emerge --sync was 148d 15h 27m 13s ago.
* IMPORTANT: 3 config files in '/etc/portage' need updating.
* See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS
* sections of the emerge man page to learn how to update config files.

!!! All ebuilds that could satisfy ">=dev-util/cmocka-1.1.1[abi_x86_64(-)]" have been masked.
!!! One of the following masked packages is required to complete your request:

The current version of portage supports EAPI '6'. You must upgrade to a
newer version of portage before EAPI masked packages can be installed.
