Let’s Encrypt root cert update issue

Dear Husarnet Users,

You may face issues with Husarnet installation and removal caused by Let’s Encrypt certificate authority root cert update. The problem is not specific to Husarnet, and this issue has hit many tech companies worldwide. You can read more here: https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/

How to fix the problem?


If you try to install Husarnet and, the installation procedure crashes, please install/update ca-certificate:

sudo apt-get install ca-certificates

And try to run installation script once more.

curl https://install.husarnet.com/install.sh | sudo bash
sudo systemctl restart husarnet


If you see errors after executing:

sudo apt-get remove husarnet

you might be forced to remove Husarnet manually (be careful to avoid typo that might be very harmful for your OS!)

sudo rm -rf /lib/systemd/system/husarnet*
sudo rm -rf /usr/bin/husarnet
sudo rm -rf /var/lib/husarnet

sudo apt-get install ca-certificates
sudo apt-get remove husarnet

Now Husarnet can be installed once more without any issues.

We already have added ca-certificaties package to Husarnet installation script, so most of you should not even notice that something happened.

Nevertheless, in case of any issues, please let us know.


Husarnet team
