Hi, urm, looking again at
N: Download is performed unsandboxed as root as file '/media/deploy/UUI/dists/buster/InRelease' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied) i wonder whether it did simply work fine as root. "N:" is probably the prefix for a note which reports some peculiarity but not a real problem. The story would be that the superuser could not do the work after downgrading itself to "_apt" and thus had to work by its own superpowers. In the failure messages of "apt-get install" we see "E:" as prefix. I guess that means "error". But i find no explanation of these markers anywhere in man dpkg-deb, dpkg, apt, apt-get. Probably it is lintian style https://www.debian.org/doc/manuals/maint-guide/checkit.en.html#lintians Whatever, try whether you now can install openssh-server.

Maybe we can present an answer after some more struggle. Have a nice day :) Thomas
