You have an unusual mix of symptoms of two known problems.

Error 3 and Error 4 usually only arise if you attempt to update an uninstalled system.
For example, if you boot off Live media and then try updating. I don't recall ever seeing this reported on an installed system so this is odd.

Error 11 is known to happen after running the Lite Tweak called Package System Repair. I suspect you may have tried running the Package System Repair tweak to fix the Error 3 and Error 4. The PSR tweak has a known bug which has been fixed, but you have to be able to update to get it. In this case running the unfixed tweak may have added another error.

Given the mix of problems, I'd suggest re-installing, but as you have already done this several times we can try to sort out the system as it is by removing the unwanted repositories.

Please boot up and open a terminal by pressing Ctrl Alt and T together.
In the terminal window that opens type in this commands to show what repositories you have.

Code:

sudo inxi -r

followed by Enter. You will be asked for your password to allow the command to run, so type it in followed by Enter

Copy the results of the command and paste them back into the thread.
