Index File - error opening zip file

A few weeks ago we have discussed on this error and this is the post.

The problem is the F-Droid Archive repository interacting with the main repo i.e. you main repo “F-Droid” which stores the apps you use from f-droid.org.

You don’t need this repo as previously mentioned because all you use are usually from the main repo, and @Licaon_Kter mentioned that it’s only for developing usages. Therefore switch off syning the “F-Droid Archive” will solve the error and won’t affect your daily usages.
