baserow baserow UPGRADE

Affected: >= 0.6.0 and < 1.1.0

Fixed in: 1.1.0

Safe to downgrade to: a release before 0.6.0

dnf --showduplicates list baserow sudo dnf downgrade baserow-<VERSION_BEFORE_0.6.0> sudo dnf versionlock add baserow

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.
