mfscripts yetishare UPGRADE

Affected: >= 3.5.2 and <= 4.5.4

Fixed in: newer than 4.5.4

Safe to downgrade to: a release before 3.5.2

1. Check installed version

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

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

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 3.5.2 (Debian / Ubuntu)

apt-cache madison yetishare sudo apt install yetishare=<VERSION_BEFORE_3.5.2> sudo apt-mark hold yetishare

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

dnf --showduplicates list yetishare sudo dnf downgrade yetishare-<VERSION_BEFORE_3.5.2> sudo dnf versionlock add yetishare

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.
