jeecg jeecg boot UPGRADE

Affected: >= 3.0 and <= 3.5.3

Fixed in: newer than 3.5.3

Safe to downgrade to: a release before 3.0

1. Check installed version

apt-cache policy jeecg-boot || rpm -q jeecg-boot || jeecg-boot --version

2. UPGRADE to newer than 3.5.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade jeecg-boot

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade jeecg-boot

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 3.0 (Debian / Ubuntu)

apt-cache madison jeecg-boot sudo apt install jeecg-boot=<VERSION_BEFORE_3.0> sudo apt-mark hold jeecg-boot

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list jeecg-boot sudo dnf downgrade jeecg-boot-<VERSION_BEFORE_3.0> sudo dnf versionlock add jeecg-boot

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.
