sewio real-time location system studio UPGRADE

Affected: >= 2.0.0 and <= 2.6.2

Fixed in: newer than 2.6.2

Safe to downgrade to: a release before 2.0.0

1. Check installed version

apt-cache policy real-time-location-system-studio || rpm -q real-time-location-system-studio || real-time-location-system-studio --version

2. UPGRADE to newer than 2.6.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade real-time-location-system-studio

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade real-time-location-system-studio

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 2.0.0 (Debian / Ubuntu)

apt-cache madison real-time-location-system-studio sudo apt install real-time-location-system-studio=<VERSION_BEFORE_2.0.0> sudo apt-mark hold real-time-location-system-studio

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

dnf --showduplicates list real-time-location-system-studio sudo dnf downgrade real-time-location-system-studio-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add real-time-location-system-studio

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.
