Since upgrading to the latest Raspbian operating system (Buster), I'm getting "Error while computing" failures on my Raspberry Pi 1B+ (this is the first generation model). This Pi was running Universe@Home successfully with an earlier version of Raspbian after I edited the cc_config.xml file in /etc/boinc-client with the following addition:

<options>
  <alt_platform>armv6l-unknown-linux-gnueabihf</alt_platform>
</options>

The above modification was taken from Message 3404: https://universeathome.pl/universe/forum_thread.php?id=394&postid=3404
Help would be appreciated. Thank you.
