mongodb laravel mongodb UPGRADE

Affected: >= 4.0.0 and < 5.11.0

Fixed in: 5.11.0

Safe to downgrade to: a release before 4.0.0

1. Check installed version

apt-cache policy laravel-mongodb || rpm -q laravel-mongodb || laravel-mongodb --version

2. UPGRADE to 5.11.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade laravel-mongodb

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 4.0.0 (Debian / Ubuntu)

apt-cache madison laravel-mongodb sudo apt install laravel-mongodb=<VERSION_BEFORE_4.0.0> sudo apt-mark hold laravel-mongodb

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

dnf --showduplicates list laravel-mongodb sudo dnf downgrade laravel-mongodb-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add laravel-mongodb

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.
