Help/Support Please Help Cydia Won't Work!

[TheRealMrMan 0 iPad Mini 11.2.6]

I'm not the newest to Cydia but i never know what I'm doing on it. i was gonna download a file manager like Filza but i can't because my cydia is broken or something every time i load it up it says "Half Installed Package" and i cant download or remove any tweaks apps or anything. i don't have any file manager on my cydia so no Ifile Filza or none of that. the 2 errors i get when i remove something is this "subprocess installed post-installation script was killed by signal (Abort trap: 6):" i also get "Sub-process /usr/libexec/cydia/cydo returned an error code (1)" I'm on ios 12.0.1 Unc0ver jailbreak I've  looked up videos on Youtube but i couldn't find anything and i don't know what to look for because i don't know whats wrong with my Cydia. What i meant when i couldn't download anything is when i tried/clicked on modify and install it showed everything working but then BAM nothing on my home screen and it has the same error and the remove but the check mark is still there so if anyone can help that'll be greatly appreciated thank you and hope to get help

Do you remember from when cydia gave you that error? Because for me it was a tweak(forgot its name) after I installed that tweak cydia gave me that error saying half installed package and then after I removed that tweak and everything was good again.

if you don’t know then I think restore rootfs is your only option
