1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.1.11 (Debian / Ubuntu)

apt-cache madison microbetrace sudo apt install microbetrace=<VERSION_BEFORE_0.1.11> sudo apt-mark hold microbetrace

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

dnf --showduplicates list microbetrace sudo dnf downgrade microbetrace-<VERSION_BEFORE_0.1.11> sudo dnf versionlock add microbetrace

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.
