We’ve made a change in the ISO build scripts so they use the development repos, dev.packages.vyos.net, as package source by default. The development repos are automatically populated by the CI server, so you always get the most recent packages.
This change only affects helium branch, hydrogen stays untouched. We will modify “–with-release-build” behaviour to use the release repos later, since helium doesn’t have a release version yet, that’s not a problem.
Note that release and development repos use different GPG keys, so when you build a development ISO, you will be asked whether you trust the key, same with installing release packages on development builds and vice versa. This is to prevent accidental installation of unstable development packages on production systems.
