xylem aquaview UPGRADE

Affected: >= 7.0.0 and < 8.0.1 · 1.60

Fixed in: 8.0.1

Safe to downgrade to: a release before 1.60

1. Check installed version

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

2. UPGRADE to 8.0.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade aquaview

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 1.60 (Debian / Ubuntu)

apt-cache madison aquaview sudo apt install aquaview=<VERSION_BEFORE_1.60> sudo apt-mark hold aquaview

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

dnf --showduplicates list aquaview sudo dnf downgrade aquaview-<VERSION_BEFORE_1.60> sudo dnf versionlock add aquaview

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.
