nextcloud tables UPGRADE

Affected: >= 0.9.0 and < 0.9.7 · >= 1.0.0 and < 1.0.2

Fixed in: 0.9.7, 1.0.2

Safe to downgrade to: a release before 0.9.0

1. Check installed version

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

2. UPGRADE to 0.9.7 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade tables

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 0.9.0 (Debian / Ubuntu)

apt-cache madison tables sudo apt install tables=<VERSION_BEFORE_0.9.0> sudo apt-mark hold tables

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

dnf --showduplicates list tables sudo dnf downgrade tables-<VERSION_BEFORE_0.9.0> sudo dnf versionlock add tables

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.
