Resolved Fresh install - apt brings messages

[Oliver Marugg]

Hi

I did fresh and clean install of Onyx and Ubuntu 16.04.
After each apt update/upgrade or so, I have following messages (I did not added any sources):

N: Ignoring file 'plesk.list.ai_back' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
W: http://autoinstall.plesk.com/debian/SITEBUILDER_17.0.15/dists/all/InRelease: Signature by key KEY_REMOVED_USER uses weak digest algorithm (SHA1)
W: http://autoinstall.plesk.com/ubuntu/LETSENCRYPT_0.0.2/dists/xenial/InRelease: Signature by key KEY_REMOVED_USER uses weak digest algorithm (SHA1)

Any ideas about those installation issues? Apt runs through as expected.
regards, oliver

Signature by key KEY_REMOVED_USER uses weak digest algorithm

Debian and Ubuntu enforce SHA256 or higher entries in the Release and/or Packages files since March.
It is a warning. This issue does not stop you from upgrading packages.

OK, thanks.
