simple password store project simple password store UPGRADE

Affected: >= 1.7.0 and < 1.7.2

Fixed in: 1.7.2

Safe to downgrade to: a release before 1.7.0

1. Check installed version

apt-cache policy simple-password-store || rpm -q simple-password-store || simple-password-store --version

2. UPGRADE to 1.7.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade simple-password-store

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade simple-password-store

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 1.7.0 (Debian / Ubuntu)

apt-cache madison simple-password-store sudo apt install simple-password-store=<VERSION_BEFORE_1.7.0> sudo apt-mark hold simple-password-store

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

dnf --showduplicates list simple-password-store sudo dnf downgrade simple-password-store-<VERSION_BEFORE_1.7.0> sudo dnf versionlock add simple-password-store

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.
