linuxfoundation dapr UPGRADE

Affected: >= 1.3.0 and < 1.15.14 · >= 1.16.0 and < 1.16.14 · >= 1.17.0 and < 1.17.5

Fixed in: 1.15.14, 1.16.14, 1.17.5

Safe to downgrade to: a release before 1.3.0

1. Check installed version

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

2. UPGRADE to 1.15.14 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade dapr

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 1.3.0 (Debian / Ubuntu)

apt-cache madison dapr sudo apt install dapr=<VERSION_BEFORE_1.3.0> sudo apt-mark hold dapr

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

dnf --showduplicates list dapr sudo dnf downgrade dapr-<VERSION_BEFORE_1.3.0> sudo dnf versionlock add dapr

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.
