openvpn connect UPGRADE

Affected: >= 3.5.1 and < 3.8.2

Fixed in: 3.8.2

Safe to downgrade to: a release before 3.5.1

1. Check installed version

apt-cache policy connect || rpm -q connect || connect --version

2. UPGRADE to 3.8.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade connect

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade connect

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 3.5.1 (Debian / Ubuntu)

apt-cache madison connect sudo apt install connect=<VERSION_BEFORE_3.5.1> sudo apt-mark hold connect

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list connect sudo dnf downgrade connect-<VERSION_BEFORE_3.5.1> sudo dnf versionlock add connect

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
