(I have already looked up many solutions (involving apk-managers or un-/reinstalling) offered in similar situations but none of them seemed to work in my case.)
When trying to update the app "Google Play services" (microG Services Core, com.google.android.gms) I get the error message "Conflicting package exists". Meanwhile other apps are complaining that Google play services are not up to date. I am at a loss because I cannot uninstall this app, and solutions using apkmanagers have also failed, perhaps due to not having root access. I also tried installing the Google play services apk from apkmirror sites, but the installer would simply say that the app could not be installed.
I am open to more radical solutions like a factory reset, but I want to be sure that would even help before I do. I have adb tools on my laptop.
I have a mostly degoogled phone (e/OS) and usually use F-Droid for my apps, and aurora store for apps (such as this one) that cannot be found on F-Droid. I am trying to update Google Play Services through the aurora store. It has always worked so far, and other apps update normally. I think this issue might have happened while I was manually updating some apps and accidentally had two updates running at the same time? I'm not entirely sure.
E/OS has its own store but it has never really worked for me and I never use it. The e/OS store always claims that all apps are up to date.
