can't update microG core from fdroid

[geg2048]

This should be possible, right?

And I am also getting: I/Xposed ( 800): FakeGApps: not returning fake signature to org.fdroid.fdroid

So is should get the real signature, but fdroid keeps saying that it's not the same.

I guess it's a different issue. Is it possible that you are now trying to install a GmsCore apk which is signed with a different key than your current version?

Btw, check out the xposed module xinstaller, that should help here.

[bonanza123]

The xinstaller option you are looking for is "confirming signature check".

[geg2048]

After some research I think I found the problem. I do actually need the fake signature from FakeGApps because the "sig" tag on the https://microg.org/fdroid/repo/index.xml does use the fake signatue.

[bonanza123]

I'm still convinced that your problem is caused by different signatures of your installed gmscore apk and the one you would like to update with. please provide a logcat of the error

@bonanza123 thank you for taking down the PR, could be a real problem at this point :) @geg2048 are you using the special repository described on https://microg.org/fdroid/ ?

Ok im going to explain it:

i checked my signature and the sha256 value of my installed app and the app of the fdroid repo they are both the same: $ keytool -list -printcert -jarfile com.google.android.gms-8489277.apk

Owner: O=NOGAPPS Project, C=DE Issuer: O=NOGAPPS Project,C=DE

Signature algorithm name: SHA256withRSA Version: 3

If you are going to download this file https://microg.org/fdroid/repo/index.xml you will see this:

8.4.89 (microG v0.2.0) 8489277 com.google.android.gms-8489277.apk 119dbdfa66120a852492d0c017a46c848c1f4a34f3ae29be620aa2de161b3abc d91564be0d13dcff260fe019eeea8cd8

sig = d91564be0d13dcff260fe019eeea8cd8 this value is generated by this tool: https://github.com/f-droid/fdroidserver/tree/master/tests/getsig and used to check the apk signature which are:

microG GsmCore apk $ java getsig com.google.android.gms-8489277.apk Result:ca625df9dd76b6002de9c94d216cf09b

Original Google apk $ java getsig GoogleServicesFramework.apk Result:d91564be0d13dcff260fe019eeea8cd8

You see that the provided signature d91564be0d13dcff260fe019eeea8cd8 is which is not the signature of the microG GsmCore apk (ca625df9dd76b6002de9c94d216cf09b). which is total logical because only FakeGApps whitelistes fdroid but the omnirom fakesignature patch does not.

I hope you understand me now. I am sorry that I didnt give a proper explanation before.

[geg2048]

@thermatk yes the offical microg fdroid repo https://github.com/microg/android_packages_apps_GmsCore/wiki/Downloads

[geg2048]

I also installed a version without the fdroid filtering and it works

[geg2048]

OK I looked around and found this https://github.com/microg/android_packages_apps_GmsCore/issues/92 which is basically my problem

[thermatk]

MaR-V-iN says in the XDA thread he might provide a solution in the coming weeks, let's wait. Meanwhile, you can update manually, no?

[geg2048]

@thermatk sure no problem there and thanks for the help

[mar-v-in]

@thermatk As ROM patches are not very dynamic and we won't see a proper adaption in all patches soon, I'd propose to go the other way round and spoof signature to F-Droid as well. This should allow FakeGapps users to use the F-Droid repo until we find a better solution...

[thermatk]

@mar-v-in the only other option at the time would be xposed-hacking the F-Droid logic :) @geg2048 will upload to XposedRepo soon
