paloaltonetworks prisma access agent UPGRADE

Affected: >= 25.7 and < 26.2.1

Fixed in: 26.2.1

Safe to downgrade to: a release before 25.7

1. Check installed version

apt-cache policy prisma-access-agent || rpm -q prisma-access-agent || prisma-access-agent --version

2. UPGRADE to 26.2.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade prisma-access-agent

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 25.7 (Debian / Ubuntu)

apt-cache madison prisma-access-agent sudo apt install prisma-access-agent=<VERSION_BEFORE_25.7> sudo apt-mark hold prisma-access-agent

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

dnf --showduplicates list prisma-access-agent sudo dnf downgrade prisma-access-agent-<VERSION_BEFORE_25.7> sudo dnf versionlock add prisma-access-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.
