linkstack linkstack UPGRADE

Affected: >= 2.7.9 and <= 4.7.7

Fixed in: newer than 4.7.7

Safe to downgrade to: a release before 2.7.9

1. Check installed version

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

2. UPGRADE to newer than 4.7.7 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade linkstack

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 2.7.9 (Debian / Ubuntu)

apt-cache madison linkstack sudo apt install linkstack=<VERSION_BEFORE_2.7.9> sudo apt-mark hold linkstack

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

dnf --showduplicates list linkstack sudo dnf downgrade linkstack-<VERSION_BEFORE_2.7.9> sudo dnf versionlock add linkstack

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.
