Just a heads up if you're running MariaDB, and try to dump a database for instance using mysqldump. The version of mysqldump is from MySQL8 by default for some reason. I don't believe I've installed it.
https://jira.mariadb.org/browse/MDEV-16555
https://mariadb.com/kb/en/export-table-error/
https://github.com/snipe/snipe-it/issues/6800#issuecomment-470990126
For reference, mysqldump 8 is now expecting a information_schema.COLUMN_STATISTICS table.
On MariaDB there is no such column in information_schema: https://jira.mariadb.org/browse/MDEV-16555
This one seems pretty big and very surprising to me, mysqldump8 just broke the MariadDB compatibility and there's not even a fix in the new Ubuntu LTS.
Workaround: snipe/snipe-it#6800 (comment)
Adding the following to the command line works --column-statistics=0 or to .my.cnf as column-statistics=0
