talend studio UPGRADE

Affected: < 7.3.1-r2022-10 · >= 8.0.0 and < 8.0.1-r2022-09

Fixed in: 7.3.1-r2022-10, 8.0.1-r2022-09

Safe to downgrade to: a release before 8.0.0

1. Check installed version

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

2. UPGRADE to 7.3.1-r2022-10 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade studio

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 8.0.0 (Debian / Ubuntu)

apt-cache madison studio sudo apt install studio=<VERSION_BEFORE_8.0.0> sudo apt-mark hold studio

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

dnf --showduplicates list studio sudo dnf downgrade studio-<VERSION_BEFORE_8.0.0> sudo dnf versionlock add studio

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.
