Linux+OwnCloud: packages cannot be authenticated

Postby peter_b » Tue Feb 07, 2017 2:59 am

Following the instructions from the OwnCloud Desktop client download page, I got the following error trying to install the owncloud-client package:

WARNING: The following packages cannot be authenticated!
libqt5keychain1 libowncloudsync0 owncloud-client-l10n owncloud-client
Install these packages without verification? [y/N] n
E: Some packages could not be authenticated

Thanks to a comment posted by FlorianFranzen, I found a fix.
The issue was that apt didn't properly load its sources, because it already had the Release file loaded before and didn't recognize a change.

Therefore, remove (=comment out) the OwnCloud repository line in /etc/apt/sources.list.d/owncloud-client.list:
Code: Select all
deb /

Then "apt-get update", uncomment the line - then "apt-get update" again.
