citrix netscaler agent UPGRADE
Affected: >= 13.0-58.30 and < 13.0-92.31 · >= 13.1-4.43 and < 13.1-53.22 · >= 14.1-4.42 and < 14.1-25.53
Fixed in: 13.0-92.31, 13.1-53.22, 14.1-25.53
Safe to downgrade to: a release before 13.0-58.30
1. Check installed version
apt-cache policy netscaler-agent || rpm -q netscaler-agent || netscaler-agent --version
2. UPGRADE to 13.0-92.31 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade netscaler-agent
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade netscaler-agent
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 13.0-58.30 (Debian / Ubuntu)
apt-cache madison netscaler-agent
sudo apt install netscaler-agent=<VERSION_BEFORE_13.0-58.30>
sudo apt-mark hold netscaler-agent
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list netscaler-agent
sudo dnf downgrade netscaler-agent-<VERSION_BEFORE_13.0-58.30>
sudo dnf versionlock add netscaler-agent
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.
