tp-shop tp-shop UPGRADE

Affected: >= 2.0.5 and <= 3.0.0

Fixed in: newer than 3.0.0

Safe to downgrade to: a release before 2.0.5

1. Check installed version

apt-cache policy tp-shop || rpm -q tp-shop || tp-shop --version

2. UPGRADE to newer than 3.0.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade tp-shop

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade tp-shop

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 2.0.5 (Debian / Ubuntu)

apt-cache madison tp-shop sudo apt install tp-shop=<VERSION_BEFORE_2.0.5> sudo apt-mark hold tp-shop

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

dnf --showduplicates list tp-shop sudo dnf downgrade tp-shop-<VERSION_BEFORE_2.0.5> sudo dnf versionlock add tp-shop

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.
