ovidentia ovidentia UPGRADE

Affected: >= 6.0.0 and <= 6.7.7

Fixed in: newer than 6.7.7

Safe to downgrade to: a release before 6.0.0

1. Check installed version

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

2. UPGRADE to newer than 6.7.7 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ovidentia

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 6.0.0 (Debian / Ubuntu)

apt-cache madison ovidentia sudo apt install ovidentia=<VERSION_BEFORE_6.0.0> sudo apt-mark hold ovidentia

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

dnf --showduplicates list ovidentia sudo dnf downgrade ovidentia-<VERSION_BEFORE_6.0.0> sudo dnf versionlock add ovidentia

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.
