Luci-ssl-openssl build fails due to libiwinfo dependency

I'm trying to build an image with imagebuilder from snapshot for the mt7620 target. While building the image the following error occurs:

Collected errors:
 * satisfy_dependencies_for: Cannot satisfy the following dependencies for luci-ssl-openssl:
 * 	libiwinfo20181126
 * opkg_install_cmd: Cannot install package luci-ssl-openssl.

It seems that snapshot has moved to a new version (libiwinfo20200105), but some package repos still contain old binaries?

are you using
