pkp.sfu open journal systems DOWNGRADE

Affected: 3.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.3

1. Check installed version

apt-cache policy open-journal-systems || rpm -q open-journal-systems || open-journal-systems --version

2. No fixed release: DOWNGRADE to a release before 3.3 (Debian / Ubuntu)

apt-cache madison open-journal-systems sudo apt install open-journal-systems=<VERSION_BEFORE_3.3> sudo apt-mark hold open-journal-systems

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list open-journal-systems sudo dnf downgrade open-journal-systems-<VERSION_BEFORE_3.3> sudo dnf versionlock add open-journal-systems

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.
