Installation without snap

I’m on debian, and i dont want to install snap.
Its possible to install snap with classique apt-get or aptitude ?

There is no official repository, but some from community are promoted: Linux packages status

But in case just manually download the latest Nextcloud archive and extract it to your desired location:
After that you can just follow the manuel installation guide, just skipping all snap stuff.

Updates should be anyway done through the internal updater.
