okfn ckan UPGRADE

Affected: < 2.10.10 · >= 2.11.0 and < 2.11.5

Fixed in: 2.10.10, 2.11.5

Safe to downgrade to: a release before 2.11.0

1. Check installed version

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

2. UPGRADE to 2.10.10 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ckan

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 2.11.0 (Debian / Ubuntu)

apt-cache madison ckan sudo apt install ckan=<VERSION_BEFORE_2.11.0> sudo apt-mark hold ckan

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

dnf --showduplicates list ckan sudo dnf downgrade ckan-<VERSION_BEFORE_2.11.0> sudo dnf versionlock add ckan

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.
