When restoring a MySQL 8 database backup on a MariaDB server, I get the following error
boby@sok-01:~/Downloads$ mysql mage2 < magento2-2021-01-27-1-54.sql
ERROR 1273 (HY000) at line 11762: Unknown collation: 'utf8mb4_0900_ai_ci'
boby@sok-01:~/Downloads$ To fix this error, open the file in a text editor, find utf8mb4_0900_ai_ci, and replace it with utf8mb4_general_ci.
I used the following sed command to do the replacement.
sed -i 's/utf8mb4_0900_ai_ci/utf8mb4_general_ci/g' magento2.sql
