Apologies, but I had to take down the latest Virtualmin 7.30.6 update. As a result, installations and updates for the Virtualmin repo will temporarily fail.
The issue was that Virtualmin 7.30.6 was accidentally built from an untested master branch.
@Joe will fix it as soon as he’s back, as I unfortunately cannot re-sign the software.virtualmin.com repo, even though the fixed packages are ready.
If you urgently need Virtualmin installations to work, please use the pre-release repo at rc.software.virtualmin.dev.
