sudo dnf upgrade camel

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

dnf --showduplicates list camel sudo dnf downgrade camel-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add camel

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.
