privatebin privatebin UPGRADE

Affected: >= 1.7.7 and < 2.0.3

Fixed in: 2.0.3

Safe to downgrade to: a release before 1.7.7

1. Check installed version

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

2. UPGRADE to 2.0.3 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 1.7.7 (Debian / Ubuntu)

apt-cache madison privatebin sudo apt install privatebin=<VERSION_BEFORE_1.7.7> sudo apt-mark hold privatebin

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

dnf --showduplicates list privatebin sudo dnf downgrade privatebin-<VERSION_BEFORE_1.7.7> sudo dnf versionlock add privatebin

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.
