[Sugar-devel] Error testing collaboration using 2 Oracle virtual machines

[ANIKET MATHUR]

Hello everyone,
I am using 2 Oracle Vm's having Ubuntu 18.04, using Sugar 0.112, both
attached to the same internal network. In the neigbourhood view of each the
buddy icon of other is shown. But when I click on `Make friend` option, the
buddy icon disappears and I have the following as the traceback

```
Traceback (most recent call last):
