Daily update and now 15.0.0 alpha

is it corect ?

i tried to update my nextcloud with the latest daily and now i have nextcloud 15.0.0 alpha is this correct ?

and after the original update i has an error mesage that the support app files were not replaced completely.

any ideas about what is going on ?

Don’t do that on a production server. Always use “stable”.

it is not really a production server.
now the problem is solved with replacing the files with the same latest version. so in place of automatic update i had to do this manually

Please only use that for testing and developing. Especially alpha version are unstable and things can break easily. beta versions and release candidates should be better and more interesting for testing for end users.
