Bugs in SSH module

[Dave Turvene - Work]

Hi Sawyer,

I'm running Ubuntu 18.04.5 (5.4.0-60-generic kernel) and a QEMU 5.1.0 build for 
x86_64.  I originally built for all targets including arm and aarch64 but it 
took too long.  I haven't seen this problem.

Good luck!
Dave

Here's my configure line

../../../configure --prefix=/opt/qemu \
                       --target-list=x86_64-softmmu \
                       --enable-debug \                
                       --enable-spice \
                       --enable-virtfs \
                       --enable-curses \
                       --enable-libusb
    

And here's a view of all my libssh package versions:

Hi Sawyer,

Oh yes, sorry it is libssl-dev. What version do you have installed? According 
to the link you sent, there's a reference to a problem with some older versions 
of libssl included with ubuntu

libssh-0.8 is detected as 0.7
https://bugs.launchpad.net/ubuntu/+source/libssh/+bug/1847514

The version I am using is

#apt list libssh-dev
Listing... Done
libssh-dev/stable,now 0.8.7-1+deb10u1 amd64 [installed]

As I said it seems to compile with libssl enabled just fine.

I assume you've done "apt update" and "apt upgrade" and all that?

Other than making sure you're using a recent version of libssl-dev I don't know 
what else to suggest.
