Safe to downgrade to: a release before 8.0.0

1. Check installed version

apt-cache policy secure-web-gateway || rpm -q secure-web-gateway || secure-web-gateway --version

2. UPGRADE to 8.2.28 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade secure-web-gateway

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade secure-web-gateway

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 8.0.0 (Debian / Ubuntu)

apt-cache madison secure-web-gateway sudo apt install secure-web-gateway=<VERSION_BEFORE_8.0.0> sudo apt-mark hold secure-web-gateway

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

dnf --showduplicates list secure-web-gateway sudo dnf downgrade secure-web-gateway-<VERSION_BEFORE_8.0.0> sudo dnf versionlock add secure-web-gateway

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.
