"Download failed" error when updating or installing apps

Saegle

Hey there, I just got a Pixel 8 pro second hand but almost new. I installed Graphene OS via the official tutorial from an arch linux PC without any issue during the process. It is my first install, so I'm very new to this. Pardon me for being a noob.

Whenever I try to update existing apps or install new ones, I get an error message:

Download failed

Unable to download [whatever I'm downloading]

Details:
javax.net.ssl.SSLProtocolException: Read error [...] Failure in SSL library, usually a protocol error [...]
[...] functions:OPENSSL_internal:BAD_DECRYPT [...]
[...] routines:OPENSSL_internal:DECRYPTION_FAILED_OR_BAD_RECORD_MAC [...]

I hope I included everything useful.
I couldn't find much online, only stackoverflows from android devs. But I'm no developper, and I didn't really get anything that they were saying.
It could also very well be a hardware issue. The last owner had some light problems on default android (tho no such error messages from what I know, it was just a bit sluggish during some operations) and gave it to me, in hopes that it was software and that installing another OS would solve it.
Can anyone help me figure out if this is solvable? Thanks!

Saegle can you check your time and date in settings?

Saegle

n3t_admin they are correct, and set to automatic

n3t_admin

that's a bummer, would've been a quick fix. Anyway, this error message suggest the SSL certificate(s) is(are) invalid. Which is either because they:
a) expired
b) mismatched

What downloads are we talking here, specifically? From a browser? If yes, which one?

Saegle

n3t_admin Downloads directly from the pre-installed app store, so an update for vanadium, or any other download on there. It's always the same message

n3t_admin

do you also get errors while browsing https sites or does it only affect downloads?

Saegle

n3t_admin no, just downloads from the app store. I was also able to download an image from a website without issue

n3t_admin

Saegle okay, that's a start. First step you could try, would be to reset storage for the App Store. To do that, long press the App Store icon while on the home screen or in the app drawer and click "App Info". You will see a section for "storage" on the page that opens. You can clear cache and clear storage for it. This will basically reset the app store to factory settings, so to speak. Try that and report how it goes. For good measure, I'd reboot the phone after doing that.

Saegle

n3t_admin Thanks for the steps! Something weird happened tho. I first managed to completely update Vanadium without issue. I thought it was resolved, but then I tried to install another app and the same error appeared again.
I'm also noticing now that the point at which the error occurs during installations seems random. Sometimes it's right away during download, sometimes at higher percents, sometimes even after the download, during the install.

n3t_admin

Saegle okay, that's pretty weird.
Can you try on a different network (for example on mobile data)?

Also, disable all VPNs if you use any.

Saegle

n3t_admin different networks, wifi or mobile data, always the same error unfortunately. No VPN either

n3t_admin

Saegle then I'm out of ideas, sadly. Maybe someone else can chime in.

Saegle

n3t_admin thanks a lot for all the help anyway! I'll keep looking for options

Probably9857

FWIW, this is beginning to sounding like a hardware problem to me. Maybe some bad RAM???

I have a feeling you would also see this just browsing, eventually, but downloading large files is triggering it more consistently (because of the amount of data).

Saegle

Probably9857 yeah that's what I'm starting to think too. At least I know now.

Saegle I agree with Probably9857 that bad RAM is possible. If you watch a non-short video (10 or 15 minutes), does it play all the way through?
