Fixed in: no fixed release known

Safe to downgrade to: a release before 6.x-1.0

1. Check installed version

apt-cache policy user-readonly || rpm -q user-readonly || user-readonly --version

2. No fixed release: DOWNGRADE to a release before 6.x-1.0 (Debian / Ubuntu)

apt-cache madison user-readonly sudo apt install user-readonly=<VERSION_BEFORE_6.x-1.0> sudo apt-mark hold user-readonly

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

dnf --showduplicates list user-readonly sudo dnf downgrade user-readonly-<VERSION_BEFORE_6.x-1.0> sudo dnf versionlock add user-readonly

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.
