Is there a way to install Safing Portmaster on Fedora SIlvernlue 38?

I’ve just installed silverblue so i’m still new to it, how can i install a firewall like portmaster?

When i launch the command ’ rpm-ostree install portmaster-installer.rpm’ i get the following Transaction in progress: new-deployment

You can cancel the current transaction with rpm-ostree cancel then when i launch ‘rpm-ostree cancel’ i get ‘‘Cancelling transaction: new-deployment’’, after that i cannot launch any commands anymore.
What should i do/look for?
thanks for any suggestions


The “transaction in progress” message that you have is because GNOME Software was likely updating the system in the background when you tried to install the package.
