Q:

android market: "Got auth failure from server -> invalidating auth tokens"

anybody know how to resolve this issue? I have an older device (Google I/O phone) and I've discovered that I can't install or upgrade any apps, no matter what I do.
I've tried rebooting, clearing all caches, deleting apps to save memory, installing a SIM card, removing the SIM card, and everything else.
When I run logcat, I see this message whenever I try to install an app:
com.android.vending.AsynchRequestRunner$1.runRequestRetryingFailure(): Got auth failure from server -> invalidating auth tokens.

Anybody have any ideas?
Update:  Also seeing this on a Samsung Moment, also running 1.5.  Is it possible that the Android Market has stopped supported 1.5?
Another update; factory reset seems to have fixed it.

A:

Just had the same issue with my good old T-Mobile G1 (Android 1.6). I tried clearing all kinds of caches and syncing data and using Google Talk and whatnot. What finally solved it was to uninstall the Android Market app updates. Then I just had to sign in again (using an app specific Google Account password) and the downloading of apps worked.
