    openvpn3-client-26-1.el9

Step 2: Install the selected version

Install the desired version (for example, version 26).

Ubuntu / Debian

  1. Install the selected version:

    sudo apt install --allow-downgrades openvpn3=26-3+noble openvpn3-client=26-3+noble

  2. Remove any unused packages:

    sudo apt autoremove -y

RHEL

  1. Downgrade the package:

    sudo dnf downgrade openvpn3-client-26-1.el9

  2. Remove any unused packages:

    sudo dnf autoremove -y

Step 3: Verify the installed version

Verify that the expected version is installed using one of the following commands.

Ubuntu / Debian 

sudo openvpn3 version

Alternatively:

sudo dpkg -l|grep openvpn3

RHEL 

sudo openvpn3 version

Alternatively:

sudo rpm -qa|grep openvpn3-client

Note

Both commands should return the same version and build number.

Step 4: Prevent automatic upgrades

Pin or lock the package to prevent it from being automatically upgraded.

Ubuntu / Debian 

sudo apt-mark hold openvpn3

RHEL 

sudo dnf versionlock openvpn3-client

Note

The dnf versionlock command requires the Versionlock plugin. If it isn't already installed, insall it with:

sudo dnf install 'dnf-command(versionlock)'
