ibm entirex DOWNGRADE

Affected: 11.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 11.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 11.1 (Debian / Ubuntu)

apt-cache madison entirex sudo apt install entirex=<VERSION_BEFORE_11.1> sudo apt-mark hold entirex

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

dnf --showduplicates list entirex sudo dnf downgrade entirex-<VERSION_BEFORE_11.1> sudo dnf versionlock add entirex

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.
