Affected: 4.18

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.18

apt-cache policy common-lisp-controller || rpm -q common-lisp-controller || common-lisp-controller --version

2. No fixed release: DOWNGRADE to a release before 4.18 (Debian / Ubuntu)

apt-cache madison common-lisp-controller sudo apt install common-lisp-controller=<VERSION_BEFORE_4.18> sudo apt-mark hold common-lisp-controller
