Bug#870202: mosh-server failing to start with a missing symbol

[Ivan Vucica]

Package: mosh
Version: 1.2.6-1+b2
Severity: important

Dear Maintainer,

Yesterday I updated almost all of my system to stretch / stable. (Stragglers
include things like php which might break some of my projects.)

Today I am no longer able to connect to my server with mosh. Running
mosh-server manually results in:

mosh-server: symbol lookup error: mosh-server: undefined symbol: _ZNK6google8protobuf11MessageLite25InitializationErrorStringB5cxx11Ev

Perhaps there is some incompatibility with libprotobuf?

Could we please patch stretch / stable?

Thank you for this report. Is it possible you have a different version of
libprotobuf in your LD_LIBRARY_PATH, or a different version of mosh-server
in your PATH?

(Do you have anything related to libprotobuf in /usr/local ?)

Good point. I did indeed have protobuf and protoc libraries lying around in
/usr/local.

I thought I checked all the stuff, but I guess I should have done that
strace I considered doing.

Thanks, sorry for the spurious bug report.
