ftb-gamepedia tilesheets UPGRADE

Affected: >= 5.0.1 and < 5.0.3

Fixed in: 5.0.3

Safe to downgrade to: a release before 5.0.1

1. Check installed version

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

2. UPGRADE to 5.0.3 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade tilesheets

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 5.0.1 (Debian / Ubuntu)

apt-cache madison tilesheets sudo apt install tilesheets=<VERSION_BEFORE_5.0.1> sudo apt-mark hold tilesheets

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

dnf --showduplicates list tilesheets sudo dnf downgrade tilesheets-<VERSION_BEFORE_5.0.1> sudo dnf versionlock add tilesheets

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.
