How to setup and use the snap version UFW in 16.04 LTS?

  • 772

Checking my UFW version I see its 0.35. However, I installed the Snap UFW and it is version 0.36pre-16.2.

So how do I use the snap version of UFW? Do I have to uninstall UFW 0.35 first?

I also uninstalled ufw (0.35) and then ran ufw version and got the following:

Could not use iptables. Please run:
  'sudo snap connect ufw:firewall-control ubuntu-core:firewall-control'

I tried running that but then got:

error: the required argument <snap>:<slot> was not provided.

Any ideas?

Here is output of snap interfaces:

  1. I installed UFW- no previous version was present- on Ubuntu Core 16.04 as below without issues:

    sudo snap install ufw

    and sudo snap interfaces confirms it's recognized:

    :firewall-control                    network-manager,ufw,wifi-ap

    UFW version I'm using:

    sudo snap list ufw
    Name  Version  Rev  Tracking  Publisher   Notes
    ufw   0.36     296  stable    canonical✓  -

    It's been a few years since you posted your issue, so maybe you ran into a bug. But as of 20190508 installing UFW installs without issue.
