A week ago I was trying to install ownCloud 10.0.2 using Softaculous auto installer and I got the error:
MYSQL: 1071 Specified key was too long.
I was going to try to upload it manually ... maybe it was a problem with Softaculous ! but before doing that I contacted my web host and they told me:
Currently ownCloud cannot be installed on our system as it does not meet our MySQL terms.
Please check this one: https://github.com/owncloud/core/issues/28007
So ... it was promised that the problem is going to be fixed on ownCloud 10.0.3 , and ownCloud 10.0.3 is already released some days ago !
So is the problem fixed before uploading this very large script?
