bmaltais kohya ss UPGRADE

Affected: >= 22.6.1 and < 24.0.1

Fixed in: 24.0.1

Safe to downgrade to: a release before 22.6.1

1. Check installed version

apt-cache policy kohya-ss || rpm -q kohya-ss || kohya-ss --version

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 22.6.1 (Debian / Ubuntu)

apt-cache madison kohya-ss sudo apt install kohya-ss=<VERSION_BEFORE_22.6.1> sudo apt-mark hold kohya-ss

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

dnf --showduplicates list kohya-ss sudo dnf downgrade kohya-ss-<VERSION_BEFORE_22.6.1> sudo dnf versionlock add kohya-ss

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.
