FIREWALL UPDATE......LINUX....turns Firewall OFF

[Condobloke]

I just received a firewall update...via update manager

BE AWARE:....Installing the update turned the firewall OFF

Click on menu...type in ufw.....and turn it back ON

I am running LM20.2....but this update will likely apply to all Linux Distros

 

[dos2unix]

Hasn't affected me, maybe just the distro's that run ufw ?

 

[Condobloke]

Debian, Ubuntu, Linux Mint

Ta for the heads up Bro' - when I come back from town I'll run updates on my Uma Cinnamon, and then correlate the result with a few others.

My Expirion is based on Buntu 20.04.3 did not affect it was still on but I was running GUFW as well, don't know if that made a difference or not

Found the smileys

LOL Yeah, they're hidden in a 3 vertical dots sub-menu.

At least it still remembers the three that I use.

Has not troubled me yet on LMDE 4... will watch for it. Thanks!

Brian, just some preliminary investigations, and too early to get a definitive finding, but I will persevere.

I used the following command to update just ufw in each of my Linux Mint 19.0 'Tara' Xfce and my/your Linux Mint 20.2 'Uma' Cinnamon.

sudo apt-get install --only-upgrade ufw

The input and output is in the Spoiler, along with my comments on before and after reboot

... and in both cases, the firewall remained active.

There may be another cause for the switchoff, if I learn anything I will let you know.
