its not working downloaded latest stable release and still i face this issue, 7 days are gone
UPM libraries have been updated to v1.6.0 upstream release. Due to this update
-lupm-i2clcd has been renamed to
-lupm-lcd. So refer to upstream repo  for any other changes that may be required in sensor mezzanine example you are trying to run.
BTW, there is already a documentation bug logged here .
well i just tried old Debian version 17.09 and its working fine, why buster have many issues , i think buster version 18.09 not stable versions… i found lots of bugs in it. either you are saying functions are deprecated or changed.
