Affected: >= 7.x-2.0 and < 7.x-2.26 · 7.x-2.0 alpha1 · 7.x-2.0 alpha2 · 7.x-2.0 alpha3 · 7.x-2.0 alpha4 · 7.x-2.0 alpha5 · 7.x-2.0 beta1 · 7.x-2.0 beta2

Fixed in: 7.x-2.26

Safe to downgrade to: a release before 7.x-2.0

1. Check installed version

apt-cache policy open-atrium || rpm -q open-atrium || open-atrium --version

2. UPGRADE to 7.x-2.26 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade open-atrium

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade open-atrium

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 7.x-2.0 (Debian / Ubuntu)

apt-cache madison open-atrium sudo apt install open-atrium=<VERSION_BEFORE_7.x-2.0> sudo apt-mark hold open-atrium

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

dnf --showduplicates list open-atrium sudo dnf downgrade open-atrium-<VERSION_BEFORE_7.x-2.0> sudo dnf versionlock add open-atrium

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.
