Repository does not have a Release file.

[Onno Steenbergen]

Since a few weeks all clients report errors when updating:

  # sudo apt update
  Get:1 file:/var/lib/landscape/client/package/binaries ./ InRelease
  Ign:1 file:/var/lib/landscape/client/package/binaries ./ InRelease
  Get:2 file:/var/lib/landscape/client/package/binaries ./ Release
  Err:2 file:/var/lib/landscape/client/package/binaries ./ Release
    File not found - /var/lib/landscape/client/package/binaries/./Release (2: No such file or directory)
  ...
  E: The repository 'file:/var/lib/landscape/client/package/binaries ./ Release' does not have a Release file.
  N: Updating from such a repository can't be done securely, and is therefore disabled by default.
  N: See apt-secure(8) manpage for repository creation and user configuration details.

I have tried reinstalling landscape-client, but it didn't help.
Via some searching I discovered that Debian repo format (https://wiki.debian.org/DebianRepository/Format#Flat_Repository_Format) for flat repositories should not require a release file. Maybe something upstream changed that caused this issue.

Simon -- isn't this a server issue?

[Onno Steenbergen (osteenbergen)]

The repo is configured as a local repository.

"deb file:///var/lib/landscape/client/package/binaries ./"

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Nafallo Bjälevik (nafallo)]

I'm seeing this on Xenial, using the Canonical Landscape Server.

[Mike Fry (mikefrygm)]

I am experiencing this same issue using on-prem Landscape 18.03 and Xenial.
