deltek vision UPGRADE

Affected: >= 7.0 and < 7.6

Fixed in: 7.6

Safe to downgrade to: a release before 7.0

1. Check installed version

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

2. UPGRADE to 7.6 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade vision

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 7.0 (Debian / Ubuntu)

apt-cache madison vision sudo apt install vision=<VERSION_BEFORE_7.0> sudo apt-mark hold vision

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

dnf --showduplicates list vision sudo dnf downgrade vision-<VERSION_BEFORE_7.0> sudo dnf versionlock add vision

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.
