apt-cache madison group-invite sudo apt install group-invite=<VERSION_BEFORE_3.0.0> sudo apt-mark hold group-invite

dnf --showduplicates list group-invite sudo dnf downgrade group-invite-<VERSION_BEFORE_3.0.0> sudo dnf versionlock add group-invite

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
