Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 16.10 (Debian / Ubuntu)
apt-cache madison tuleap sudo apt install tuleap=<VERSION_BEFORE_16.10> sudo apt-mark hold tuleap

dnf --showduplicates list tuleap sudo dnf downgrade tuleap-<VERSION_BEFORE_16.10> sudo dnf versionlock add tuleap
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.
