isode m-vault UPGRADE

Affected: >= 16.0v0 and <= 17.0v3

Fixed in: newer than 17.0v3

Safe to downgrade to: a release before 16.0v0

1. Check installed version

apt-cache policy m-vault || rpm -q m-vault || m-vault --version

2. UPGRADE to newer than 17.0v3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade m-vault

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade m-vault

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 16.0v0 (Debian / Ubuntu)

apt-cache madison m-vault sudo apt install m-vault=<VERSION_BEFORE_16.0v0> sudo apt-mark hold m-vault

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

dnf --showduplicates list m-vault sudo dnf downgrade m-vault-<VERSION_BEFORE_16.0v0> sudo dnf versionlock add m-vault

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.
