Can't install app - INSTALL_PARSE_FAILED_NO_CERTIFICATES

AndroidNoob523

I just installed GrapheneOS on my brand new Pixel 10.
Thank you so much for this project and all the efforts put into it.

Most of my applications' installation works fine, but I have been stumbling upon an odd one.

I am trying to install BEKB TWINT - https://play.google.com/store/apps/details?id=ch.bekb.twint

I am using the Play Store provided by the built-in GrapheneOS's store.

I checked the logs of the Play Store app and found this :

As anyone stumbled upon such an error before ? How do I fix this ? Is this something I can even do ? It seems like it's an error that only the developer of the app can fix.

Hopefully someone can relate and help me fix this !

AndroidNoob523 I tried but did not manage to get it installed.

Novalissoide

AndroidNoob523 brand new Pixel 10.

I tried on a P6a, so not likely a fault of the P10

Though four of their other apps on Play intalled just fine;
https://play.google.com/store/apps/details?id=ch.bekb.BEKBApp
https://play.google.com/store/apps/details?id=ch.bkb.digital.banking.android
https://play.google.com/store/apps/details?id=ch.blkb.mobile.android
https://play.google.com/store/apps/details?id=ch.bekb.smartLogin

So, something about
https://play.google.com/store/apps/details?id=ch.bekb.twint
is off, it seems.

Novalissoide

AndroidNoob523 This version of the app installed correctly:

ch.blkb.twint
versionCode 25808000

Try search for the app again, for me it showed after a couple of tries.

AndroidNoob523

Wow, thanks so much for the research, I'll check it out tomorrow.
I will report back if I make it work somehow.

AndroidNoob523

I just noticed - ch.blkb.twint is not the same application as the one I mentioned - ch.bekb.twint

Novalissoide

AndroidNoob523 Yes, I noticed that after install, but first I thought it was only the app language that differed.
Today however, I got the correct app to download, and when attemting install, it gets rejected with exactly the error that you got;

INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl1294646933.tmp/config.xxhdpi using APK Signature Scheme v3: Failed to parse/verify signer #0 block: Failed to verify SHA512withRSA signature: com.android.org.conscrypt.OpenSSLX509CertificateFactory$ParsingException: Error parsing public key: Error parsing public key

On the P6 as well ? If so, I might need to give up on GrapheneOS :( !

Novalissoide

AndroidNoob523 But wait, all those apps by the same publisher installs properly, the one that isn't at present also lagging behind in terms of updates. So, it may very well be that it will get up to normal condition, might be a bug they're working on right now. Maybe you could try contacting them about it?

AndroidNoob523

Novalissoide I did that, I am supposed to have a call in a couple of hours. Without surprise, it's a banking app.

I will post once more when I have news.

AndroidNoob523

Called the support. Their developers are aware of the issue and they are working on it for a couple of days now haha... So I guess, I just need to wait for the update.

Novalissoide

AndroidNoob523 Oh thats an exciting wait. Keep us in the know, and good luck! 🫡

AndroidNoob523

Out of curiousity and being left without new news from the bank, I tried to install it on a Pixel 9 (using Android Studio emulator). It did work.

I don't have access to my Pixel 10 now but I'll try tonight.

AndroidNoob523

It did not work... Anyway I can emulate a Pixel 10 ? There is not emulator available in Android Studio.

AndroidNoob523 I also tried a previous version of the app, 21820, and that threw the same error. The latest version is still from 21 October 2025, so there seems like they either still trying to fix this, or that they might have given up trying.
Now, if GrapheneOS is the system rejecting this app, to me it comes across as GrapheneOS being the entity with the security standards good enough to actually refuse an unsafe app. Would it be worth the risk running it on a less strict system? I wouldn't, but it's up to you to judge. 🫤

From what I can read from the logs, it's seems like it's an error of the dev, the way they sign the app is not supported anymore.

They haven't worked on it actively for sure, since it's the end of the year and many employees where on vacation.

They said they were aware of the problem and they could not give me an estimate as of when they will fix it.

I guess I'll move my assets to another bank...

EDIT: Out of curiosity, did the installation work on a Google Pixel 10 without GrapheneOS ?

Novalissoide

AndroidNoob523 did the installation work on a Google Pixel 10 without GrapheneOS

I would test this if only I had a P10.

I've reproduced this issue on stock OS on Pixel 8: https://github.com/GrapheneOS/os-issue-tracker/issues/6951

Novalissoide

muhomorr thanks a ton for this! 🫡
Then it seems like the common denominator is arguably Pixels generally.
