jenkins bitbucket server integration UPGRADE

Affected: >= 2.1.0 and < 4.1.4

Fixed in: 4.1.4

Safe to downgrade to: a release before 2.1.0

1. Check installed version

apt-cache policy bitbucket-server-integration || rpm -q bitbucket-server-integration || bitbucket-server-integration --version

2. UPGRADE to 4.1.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade bitbucket-server-integration

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade bitbucket-server-integration

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 2.1.0 (Debian / Ubuntu)

apt-cache madison bitbucket-server-integration sudo apt install bitbucket-server-integration=<VERSION_BEFORE_2.1.0> sudo apt-mark hold bitbucket-server-integration

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

dnf --showduplicates list bitbucket-server-integration sudo dnf downgrade bitbucket-server-integration-<VERSION_BEFORE_2.1.0> sudo dnf versionlock add bitbucket-server-integration

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.
