mindspore mindspore UPGRADE

Affected: >= 1.0.0 and < 1.3.0 · 0.7.0 beta

Fixed in: 1.3.0

Safe to downgrade to: a release before 0.7.0

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 0.7.0 (Debian / Ubuntu)

apt-cache madison mindspore sudo apt install mindspore=<VERSION_BEFORE_0.7.0> sudo apt-mark hold mindspore

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

dnf --showduplicates list mindspore sudo dnf downgrade mindspore-<VERSION_BEFORE_0.7.0> sudo dnf versionlock add mindspore

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.
