jeewms jeewms UPGRADE

Affected: >= 3.2 and <= 3.7

Fixed in: newer than 3.7

Safe to downgrade to: a release before 3.2

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

2. UPGRADE to newer than 3.7 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade jeewms

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 3.2 (Debian / Ubuntu)

apt-cache madison jeewms sudo apt install jeewms=<VERSION_BEFORE_3.2> sudo apt-mark hold jeewms

dnf --showduplicates list jeewms sudo dnf downgrade jeewms-<VERSION_BEFORE_3.2> sudo dnf versionlock add jeewms

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.
