FWIW, people using Electra are essentially using a fork of everything I’ve ever done that was put together by coolstar with no thought to how it would affect anything else I’m working on or will be releasing, either in the near future or in the distant future; so, if you have installed Electra, I would strongly recommend never installing any of the packages I push going forward: I have done no testing with Electra nor do I have any interest at all in spending time I don’t really have to try to figure out how to maintain compatibility with Electra.
The new version of Cydia I’m going to be pushing will probably not work without the new version of Substrate, and I’m pretty sure the new version of Substrate I’m going to be pushing will not work on Electra (it definitely doesn’t work on LiberiOS, which is a “vaguely supported upgrade path”; it is possible it will sort of “half” work on Electra, and there’s one design option which might allow it to sort of work, but I’ve been leaning towards two other ways of doing it that I already have working, one of which simply could not ever function correctly on Electra and the other one which simply is assuming a bootstrap process that is based on the Cydia jailbreak instead of on Electra).
