using the suggested code ``` cd /path/to/dumb-jump cask make test-all-in-docker ``` failed with version emacs-24.4-travis: [dumb-jump-1646151161-emacs-24.4-travis.log](https://github.com/jacktasia/dumb-jump/files/8163116/dumb-jump-1646151161-emacs-24.4-travis.log) By the way, is the `cask` command before the `make test-all-in-docker` necessary ? Thanks
