myserver myserver DOWNGRADE

Affected: 0.8.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.8.5

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.8.5 (Debian / Ubuntu)

apt-cache madison myserver sudo apt install myserver=<VERSION_BEFORE_0.8.5> sudo apt-mark hold myserver

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

dnf --showduplicates list myserver sudo dnf downgrade myserver-<VERSION_BEFORE_0.8.5> sudo dnf versionlock add myserver

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.
