grafana snowflake UPGRADE

Affected: >= 1.14.7 and <= 1.14.12

Fixed in: newer than 1.14.12

Safe to downgrade to: a release before 1.14.7

1. Check installed version

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

2. UPGRADE to newer than 1.14.12 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade snowflake

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 1.14.7 (Debian / Ubuntu)

apt-cache madison snowflake sudo apt install snowflake=<VERSION_BEFORE_1.14.7> sudo apt-mark hold snowflake

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

dnf --showduplicates list snowflake sudo dnf downgrade snowflake-<VERSION_BEFORE_1.14.7> sudo dnf versionlock add snowflake

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.
