2. UPGRADE to 6.0.70 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade trytond

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 6.0.0 (Debian / Ubuntu)

apt-cache madison trytond sudo apt install trytond=<VERSION_BEFORE_6.0.0> sudo apt-mark hold trytond

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

dnf --showduplicates list trytond sudo dnf downgrade trytond-<VERSION_BEFORE_6.0.0> sudo dnf versionlock add trytond

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.
