Installed version: 1.3.9.36089-trusty
New version: 1.3.10.36104-trusty

The update is available in Update Manager level 3 but returns the following error:

W: Failed to fetch http://apt.insynchq.com/mint/pool/non-free/i/insync/insync_1.3.10.36104-trusty_amd64.deb

Thanks in advance.

@SaidulHassan: There is a newer version available. Please re-run sudo apt-get update to update the repository information.

Hi @lpugoy Thank you for the prompt response. Unfortunately apt-get update returns GPG error now.

And Update Manager GUI still shows the latest version mentioned earlier[quote=“SaidulHassan, post:1, topic:8192”]
Installed version: 1.3.9.36089-trusty
New version: 1.3.10.36104-trusty

PS. I am not sure if I used .deb or PPA or both to install/upgrade Insync. Could this be the source of the problem? Most of all I have been using Insync on this machine for over a year and having problem with this update only.

@SaidulHassan: Apologies for that. Please try the steps shown here to fix the issue: New Insync version: 1.3.11.

Thank you. It solved the problem.
