jabber exodus DOWNGRADE

Affected: 0.10

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.10

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.10 (Debian / Ubuntu)

apt-cache madison exodus sudo apt install exodus=<VERSION_BEFORE_0.10> sudo apt-mark hold exodus

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

dnf --showduplicates list exodus sudo dnf downgrade exodus-<VERSION_BEFORE_0.10> sudo dnf versionlock add exodus

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.
