Aurora Store installs fail with a "Server busy" error as users blame Google

Aurora Store users have been running into failures when installing apps. In an issue opened on the project's GitLab tracker on August 31 (#1566), a user reports that Aurora Store, including the Nightly build dated 2026-08-31, returns the message "&$Server busy, please try again later" when installing an application through an anonymous account.

According to the report, the problem persists with a VPN, after clearing the cache, refreshing the anonymous account, force-closing the app or restarting the device. The environment listed is a Fairphone 5 running Android 16, Aurora Store 4.8.4 and CalyxOS 7.2.4.20.

What other users report

Commenters confirm the issue on GrapheneOS, CalyxOS, standard Android and a Samsung Galaxy S23; one says it has lasted more than a week and is getting worse. The behaviour is inconsistent: for some, refreshing accounts or clearing the app's data and cache helps, one user succeeds only on the fifth or sixth attempt, and another switches VPN exit countries to find one that works.

Logging in with a Google account is offered as a workaround, though some users object that this defeats the purpose of Aurora, whose appeal is avoiding the Play Store and a Google account. Private (paid) accounts reportedly still work, but one user says a paid app moved between devices can no longer be upgraded and shows "App not purchased / unavailable in your country".

Possible causes

One theory is that Google is restricting downloads outside the Play Store. A more technical one notes that Aurora Store and the Play Store both send requests to android.clients.google.com, so the problem is probably not tied to a specific operating system but to a changed response schema on Google's side that Aurora cannot parse yet.

The error string itself supports that theory: the stray "&$" characters look like an unparsed response. Another hypothesis points to throttling of the shared pool of anonymous accounts, since many users manage one successful install before it breaks again. So far, none of the explanations has been officially confirmed.

What it means in practice

Aurora Store matters most to people who avoid Google services — users of GrapheneOS, CalyxOS and LineageOS who either do not have the Play Store or deliberately steer clear of it. In such setups, Aurora's anonymous mode is one of the main channels for installing and updating apps.

Users are also asking for a more informative error message that says which service is down and drops the "&$" artifacts. Until the cause is established, the assumption that the restriction comes from Google and affects anonymous accounts remains unconfirmed.
