universityofcalifornia boinc client DOWNGRADE

Affected: 7.2.33

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.2.33

1. Check installed version

apt-cache policy boinc-client || rpm -q boinc-client || boinc-client --version

2. No fixed release: DOWNGRADE to a release before 7.2.33 (Debian / Ubuntu)

apt-cache madison boinc-client sudo apt install boinc-client=<VERSION_BEFORE_7.2.33> sudo apt-mark hold boinc-client

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

dnf --showduplicates list boinc-client sudo dnf downgrade boinc-client-<VERSION_BEFORE_7.2.33> sudo dnf versionlock add boinc-client

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.
