smb4k smb4k DOWNGRADE

Affected: 0.4 · 0.5 · 0.6 · 0.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.4

1. Check installed version

apt-cache policy smb4k || rpm -q smb4k || smb4k --version

2. No fixed release: DOWNGRADE to a release before 0.4 (Debian / Ubuntu)

apt-cache madison smb4k sudo apt install smb4k=<VERSION_BEFORE_0.4> sudo apt-mark hold smb4k

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list smb4k sudo dnf downgrade smb4k-<VERSION_BEFORE_0.4> sudo dnf versionlock add smb4k

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.
