1password 1password UPGRADE

Affected: >= 7.7.0 and < 7.8.7

Fixed in: 7.8.7

Safe to downgrade to: a release before 7.7.0

1. Check installed version

apt-cache policy 1password || rpm -q 1password || 1password --version

2. UPGRADE to 7.8.7 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade 1password

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade 1password

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 7.7.0 (Debian / Ubuntu)

apt-cache madison 1password sudo apt install 1password=<VERSION_BEFORE_7.7.0> sudo apt-mark hold 1password

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

dnf --showduplicates list 1password sudo dnf downgrade 1password-<VERSION_BEFORE_7.7.0> sudo dnf versionlock add 1password

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.
