intelliantech remote access DOWNGRADE

Affected: 3.18

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.18

1. Check installed version

apt-cache policy remote-access || rpm -q remote-access || remote-access --version

2. No fixed release: DOWNGRADE to a release before 3.18 (Debian / Ubuntu)

apt-cache madison remote-access sudo apt install remote-access=<VERSION_BEFORE_3.18> sudo apt-mark hold remote-access

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

dnf --showduplicates list remote-access sudo dnf downgrade remote-access-<VERSION_BEFORE_3.18> sudo dnf versionlock add remote-access

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.
