snowflake snowflake connector UPGRADE

Affected: >= 2.0.12 and < 4.3.0

Fixed in: 4.3.0

Safe to downgrade to: a release before 2.0.12

1. Check installed version

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

2. UPGRADE to 4.3.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade snowflake-connector

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 2.0.12 (Debian / Ubuntu)

apt-cache madison snowflake-connector sudo apt install snowflake-connector=<VERSION_BEFORE_2.0.12> sudo apt-mark hold snowflake-connector

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

dnf --showduplicates list snowflake-connector sudo dnf downgrade snowflake-connector-<VERSION_BEFORE_2.0.12> sudo dnf versionlock add snowflake-connector

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.
