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
