openlibrary openlibrary UPGRADE

Affected: >= 2016-07-0 and <= 2021-12-22

Fixed in: newer than 2021-12-22

Safe to downgrade to: a release before 2016-07-0

1. Check installed version

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

2. UPGRADE to newer than 2021-12-22 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade openlibrary

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 2016-07-0 (Debian / Ubuntu)

apt-cache madison openlibrary sudo apt install openlibrary=<VERSION_BEFORE_2016-07-0> sudo apt-mark hold openlibrary

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

dnf --showduplicates list openlibrary sudo dnf downgrade openlibrary-<VERSION_BEFORE_2016-07-0> sudo dnf versionlock add openlibrary

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.
