[Sugar-devel] Collaboration Between Activities Fail with Fedora 29 SoaS

Based on my previous conversations with you, you had indicated you were 
using Fedora 29 32-bit SoaS. Please confirm that this is still the case. 
I have changed the subject line to reflect this.

I believe you are encountering the issue which we thought we had fixed 
with a previous patch (see https://github.com/sugarlabs/sugar/issues/814 
). This patch is now upstream in F29, but _only_ if you use the updated 
32-bit SoaS image, which is not yet generally available. Even with the 
fix in place, collaboration still fails with the same message.

After starting Sugar, open the Terminal, and type 'grep key 
~/.sugar/default/logs/shell.log' If you see a message which says "ERROR 
root: Error parsing public key" then you are running into a bug that has 
been present in the last several versions of Fedora, and completely 
breaks collaboration. The underlying problem is still not fully 
understood, however we know it's related to SSH keys.

Additionally, for collaboration to function, you must also make sure 
that your Ethernet interfaces have IP addresses (self-assigned is fine), 
and that there is a default route set on each computer that is 
attempting to collaborate. You can check this from the terminal with "ip 
route", and if there is no line that starts with "default" or no output 
at all, then there is no default route set, and collaboration will not work.

Here is an example of the output of shell.log which shows the error:
