classic snap fails to find libraries

[Leo Arias]

Hello,

I'm testing the classic mode and aliases making a snap for mosh.
When I try to run it, I get this error:

$ mosh 192.168.122.29 mosh-client: error while loading shared
libraries: libprotobuf.so.9: cannot open shared object file: No such
file or directory Died at /snap/mosh/x1/bin/mosh line 311.

When I build the snap without classic mode, that library is in
prime/usr/lib/x86_64-linux-gnu/. With devmode, it is not included in
the snap.

Here is my yaml: https://github.com/elopio/mosh/blob/snapcraft/snapcraft.yaml

Am I doing something wrong in there?
