Affected: 6.0.9

Fixed in: no fixed release known

Safe to downgrade to: a release before 6.0.9

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 6.0.9 (Debian / Ubuntu)

apt-cache madison sentry sudo apt install sentry=<VERSION_BEFORE_6.0.9> sudo apt-mark hold sentry

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

dnf --showduplicates list sentry sudo dnf downgrade sentry-<VERSION_BEFORE_6.0.9> sudo dnf versionlock add sentry

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.
