Good evening Nextcloud community,

I had NC running at 20.0.3.1 on my Raspberry Pi (NGINX & MariaDB)
I decided to upgrade to NC 21.0.0 beta1 and I got an Error:

Has someone an idea what could be wrong here?
If you need more specific information (config/logs etc.) you have to tell me how to get those information.

Thank you and stay healthy
Tim S.

Thanks for replying, I have a solution.

I searched for “Database error when running migration latest for app core” in my logs and found that one error was “Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes”

What I did:
go to database
use nextcloud;
set global innodb_large_prefix=on;
set global innodb_file_format=Barracuda;
and after that I did occ maintenance:repair

after that I had to run the updater 2 times and then it worked.

it’s nice that you decided to take part in beta-testing the new version.

if you run across errors pls don’t post them on the forum but on github.
