I have been trying to repair the GitLab CI, and I'm stuck on clasp. Whatever I try to do with clasp docker images -- and I've tried the clfoundation ones, the clasp-devel ones and even made one myself -- I get an error in the GitLab pipeline trying to start up the image. For example: ``` Using docker image sha256:5880b3b4b01af70bcf79360e28e2e9e6adbfe9599f6fc61b6815a9ebac6aea7c for rpgoldman/clasp-for-iterate:latest with digest rpgoldman/clasp-for-iterate@sha256:31d928fe1cd7e3419daf79610babe0a75d2aa7eddf34d85cc75d11831e302967 ... shell not found ``` See [this pipeline transcript](https://gitlab.common-lisp.net/rgoldman/iterate/-/jobs/42061) This is a *stellar* error message! ;-) Anyone know what it means? I did some googling, but no dice. I have tried firing up this image myself and then running `make test l=clasp` in it, and the test works fine. So it's something about the interaction between the docker image and GitLab but I have no idea WTF that could be. Any suggestions? Or do I just need to give up testing on clasp? I don't want to do that, but it seems a lot better to test iterate on n - 1 lisp implementations than to test it on zero implementations. Thanks!
