filereplicationpro file replication pro DOWNGRADE

Affected: 7.5.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.5.0

1. Check installed version

apt-cache policy file-replication-pro || rpm -q file-replication-pro || file-replication-pro --version

2. No fixed release: DOWNGRADE to a release before 7.5.0 (Debian / Ubuntu)

apt-cache madison file-replication-pro sudo apt install file-replication-pro=<VERSION_BEFORE_7.5.0> sudo apt-mark hold file-replication-pro

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

dnf --showduplicates list file-replication-pro sudo dnf downgrade file-replication-pro-<VERSION_BEFORE_7.5.0> sudo dnf versionlock add file-replication-pro

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.
