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 4.0.0 (Debian / Ubuntu)

apt-cache madison camel sudo apt install camel=<VERSION_BEFORE_4.0.0> sudo apt-mark hold camel
