Insync won't start after linux mint upgrade


I had insync working properly in all my Linux computers.

Recently I installed recommended upgrades for one of my systems and I noticed that insync was not running. I tried to run it manually, but I got no reply when running

insync start

Then when issuing insync show I got a reply that insync was not running.

To figure out what was happening then I ran:
insync-headless start --no-daemon

For which I got the following output:

Traceback (most recent call last):
File “”, line 6, in
File “”, line 128, in
File “”, line 125, in
File “isyncd/linux/headless/”, line 49, in run

ImportError: /usr/lib/insync/ version `CXXABI_1.3.8’ not found (required by /usr/lib/x86_64-linux-gnu/

These are the details of my mint version:

EDITION=“Cinnamon 64-bit”
DESCRIPTION=“Linux Mint 18 Sarah”
GRUB_TITLE=Linux Mint 18 Cinnamon 64-bit

How can I solve this problem?
