3ds delmia apriso UPGRADE

Affected: >= 2020 and < 2025

Fixed in: 2025

Safe to downgrade to: a release before 2020

1. Check installed version

apt-cache policy delmia-apriso || rpm -q delmia-apriso || delmia-apriso --version

2. UPGRADE to 2025 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade delmia-apriso

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 2020 (Debian / Ubuntu)

apt-cache madison delmia-apriso sudo apt install delmia-apriso=<VERSION_BEFORE_2020> sudo apt-mark hold delmia-apriso

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

dnf --showduplicates list delmia-apriso sudo dnf downgrade delmia-apriso-<VERSION_BEFORE_2020> sudo dnf versionlock add delmia-apriso

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.
