"can't create transaction lock on" when installing MS Edge (blue-build)

General

Here’s my blue-build recipe. I’m trying to installl MS Edge.
I’m using the rpm-ostree module for that.
I added the repo (https://packages.microsoft.com/yumrepos/edge/config.repo) and the package itself (microsoft-edge-stable).

Here’re the logs: Add edge-specific repo and install it · marcinjahn/mj-os@7eaf0e0 · GitHub

Here’s the error from the logs:

#30 51.90 Installing: microsoft-edge-stable-124.0.2478.80-1.x86_64 (edge-yum)
#30 63.30 error: can't create transaction lock on /usr/share/rpm/.rpm.lock (Resource temporarily unavailable)
#30 63.30 error: /tmp/microsoft.sig.FrEsTe: key 1 import failed.

Does anyone have an idea of how to fix it?
