Calculating dependencies  . ... done!

!!! All ebuilds that could satisfy
">=app-crypt/openpgp-keys-gentoo-release-20180706" have been masked.
!!! One of the following masked packages is required to complete your
request:
- app-crypt/openpgp-keys-gentoo-release-20191030::gentoo (masked by: EAPI 7)

The current version of portage supports EAPI '6'. You must upgrade to a
newer version of portage before EAPI masked packages can be installed.
(dependency required by
"sys-apps/portage-9999::gentoo[-build,rsync-verify]" [ebuild])
(dependency required by "sys-apps/portage" [argument])

man page or refer to the Gentoo Handbook.
