[BUG] An error occurred during a git operation during clone/pull

[Trouv]

Describe the bug

Setting up the app for the first time on a new phone. Getting an error when attempting to clone the repo for the first time. The error is different depending on which type of SSH key I use (generated in the app)..

RSA:

Supplied key (android.security.keystore2.AndroidKeyStoreRSAPrivateKey) is not a RSAPrivateKey instance

ECDSA:

cannot identify EC private key: java.security.InvalidKeyException: no encoding for EC private key

Related to this, I'm actually now getting the latter on my old phone too, when I try to pull after updating to the latest snapshot. I updated to the latest snapshot because the version I was using was running into #712

Steps to reproduce

Steps to reproduce the behavior on a fresh install with no repo:

1. Go to Settings > Repository > Authentication key > Generate SSH key pair
2. Plug in public key to git server
3. In Settings > PGP settings > Key manager, import gpg key from file
4. Let's Go > Clone Remote Repo > Clone (insert repository details, use public-key)

(I tried the above on 1.16.0 and the latest snapshot)

Or, with an existing repo on latest snapshot...

1. Swipe down to pull

Expected behavior

No error, successfully clone/pull git repo.

Screenshots

No response

Device information

• Device: Google Pixel 10 (attempting clone) and Motorola Edge 2025 (attempting pull)
• OS: GrapheneOs/Android16 and Android 15, respectively
• App version: 1.16.0/latest snapshot and latest snapshot, respectively

Additional context

No response

Confirmed. After recent Google Play Services update, Android Keystore provided keys do not work anymore, unless dependency sshj is downgraded to v0.39.0.

For now, would you please try the new PGP authentication option?

[Trouv]

yeah that works for me. Thanks

[agrahn]

I think I will have to disable the in-app generated SSH key option for now. With sshj downgraded, one cannot use more modern Ed25519 keys that are available via the PGP authentication option.

This functionality (Android Keystore-provided SSH keys) was brought back by PR #786 and is available in the snapshot version.
