As the title says, is there any way to make NC21 work with MySQL 8(.0.23)?
I just downloaded the NC 18.104.22.168 tarball and installed it on a Kubuntu 20.04.1 LTS server. I also installed all of the missing php modules. I was able to get to the Installation Wizard web page at http://localhost/nextcloud, but therein lies the problem.
I entered an existing username and password combination for my MySQL server on the same host. Despite that, the NC Installation Wizard says:
**Error** MySQL username and/or password not valid You need to enter details of an existing account.
I tried another existing account, and received the same error. I created a brand new user, and received the same error. I created a php test script to confirm that php is not the problem, and my test script is able to connect to the database as each of those users, through Apache and a web browser.
The Apache error log reports only:
[Tue Feb 23 18:42:44.234214 2021] [access_compat:error] [pid 17489] [client 192.168.1.88:44024] AH01797: client denied by server co nfiguration: /var/www/nextcloud/data/htaccesstest.txt
All of the users were granted “all” permissions to the NC database, and permissions were flushed. I restarted MySQL, as well. I tried with and without specifying the MySQL port – as suggested by the Wizard.
All to no avail, as NextCloud remains unable to connect to MySQL.
I tried accounts authenticated by MySQL Native passwords as well as SHA2 passwords – neither work.
Of potential interest, when I use a non-existing database user, I receive this different error:
**Error** Error while trying to create admin user: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000]  Access denied for user 'nobody'@'localhost' (using password: YES)
What, if anything, can be done to get NextCloud to work with MySQL?
Thanks in advance.
