bootloader My Wireguard app says: "This application is corrupt. Please re-download the APK from the website linked below. After, uninstall this application, and reinstall it from the downloaded APK."

How was it obtained?

      de0u It was happened after updated and rebooted a new version of GOS. This only happened in my main profile, the Wireguard app in my secondary profile doesn't got affected by this problem.

        The Wireguard app was previously installed from Aurora Store.

        Correction: the problem started after I updated and rebooted my OS, AND Aurora Store as well. I suspect this might has to do something with the problem, but I still can't find much by searching the web. So if anyone have any idea what this problem might be and what to do, I appreciate every comments!

        @bootloader I may be wrong but I think it is because it was installed by Aurora Store. I vaguely remember something about this issue before. If it detects the installation method as Aurora Store, it can cause problems. And I think it works in secondary profiles because it can't detect it was installed by Aurora Store from another profile. So if you install again it from the Play Store, it may fix the issue. I am not 100% sure but definitely remember something like this happened before

          If by any chance you're already using Obtainium (or might be interested in using it), you can set up Wireguard through it using below instructions:

          Source URL: https://apt.izzysoft.de/fdroid/repo/
          Override Source: Fdroid Third Party Repo
          App ID or Name: com.wireguard.android

            roamer4223 That would make sense! Thank you for your comment.

            Btw in this case is it the Wireguard app developers restricting the app from Aurora Store?

                bootloader no problem, hope it helps. Let me know if you try it and it works.

                If that is the issue, then it must be the Wireguard devs, I suppose.

                Also, as @Dumdum says, Obtainium is a good choice for keeping apps updated. I use it for quite a few apps.

                  Meanwhile my problem was further escalated: now there is other apps, what I uninstalled from FDroid and now I cannot install from Aurora Store (but I can reinstall them from FD). Maybe my Aurora Store update is broken? Is it a good idea to try to reinstall Aurora Store?

                    bootloader these apps, are you sure you have uninstalled them from every user/work profile on your device first? Otherwise there would be a conflict as F-Droid apps are signed with a different key
