hi @jhunyan ,
Try it after replacing your sql/patch.sql file with the following:
https://raw.githubusercontent.com/openemr/openemr/dc1947df370cde40c49ced6e03884c47d8d6437f/sql/patch.sql
Let me know if this works. It looks like this is an issue in older mysql/mariadb versions. Luckily, it doesn’t impact anything else in the patch (the only thing this error stops is the importing of the covid icd10 codes).
thanks,
