sonicwall sma8200v UPGRADE
Affected: < 12.4.3-03526 · >= 12.5.0 and < 12.5.0-02952
Fixed in: 12.4.3-03526, 12.5.0-02952
Safe to downgrade to: a release before 12.5.0
1. Check installed version
apt-cache policy sma8200v || rpm -q sma8200v || sma8200v --version
2. UPGRADE to 12.4.3-03526 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade sma8200v
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade sma8200v
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 12.5.0 (Debian / Ubuntu)
apt-cache madison sma8200v
sudo apt install sma8200v=<VERSION_BEFORE_12.5.0>
sudo apt-mark hold sma8200v
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list sma8200v
sudo dnf downgrade sma8200v-<VERSION_BEFORE_12.5.0>
sudo dnf versionlock add sma8200v
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.
