Looks like some missing dependencies. Have you tried apt?

[asifhs 1]

Following is my attempt at installing all the dependencies.

wget http://ftp.br.debian.org/debian/pool/main/o/openssl/libssl1.1_1.1.0f-3+deb9u1_amd64.deb ;
dpkg --install libssl1.1_1.1.0f-3+deb9u1_amd64.deb ;# Successful

wget http://ftp.br.debian.org/debian/pool/main/i/icu/libicu57_57.1-6+deb9u1_amd64.deb ;
dpkg --install libicu57_57.1-6+deb9u1_amd64.deb ;# Successful

# wget http://archive.ubuntu.com/ubuntu/pool/main/d/double-conversion/libdouble-conversion1v5_2.0.1-3ubuntu2_amd64.deb
# dpkg --install libdouble-conversion1v5_2.0.1-3ubuntu2_amd64.deb ;# Already installed.
wget http://ftp.br.debian.org/debian/pool/main/d/double-conversion/libdouble-conversion1_2.0.1-4_amd64.deb ;
dpkg --install libdouble-conversion1_2.0.1-4_amd64.deb ;# Conflict with libdouble-conversion1v5.

wget http://ftp.br.debian.org/debian/pool/main/q/qtbase-opensource-src/libqt5core5a_5.7.1+dfsg-3+b1_amd64.deb ;
dpkg --install libqt5core5a_5.7.1+dfsg-3+b1_amd64.deb ;# Dependency failure: libdouble-conversion1 (>= 2.0.0)

dpkg --install synergy_1.10.0.stable_b36+275cdc1c_debian_amd64.deb ;# Dependency failure: libqt5core5a (>= 5.7.1)

Summary
synergy_1.10.0 requires:
   libqt5core5a_5.7.1 requires:
      libdouble-conversion1 conflicts with:
         libdouble-conversion1v5 needed by:
            libqt5qml5 ... which is needed by many other packages!
Details

1. Ubuntu 16.04 already has libdouble-conversion1, but it is named "libdouble-conversion1v5".
2. When trying to install libqt5core5a_5.7.1, the dependency "libdouble-conversion1" needs to be met.
3. So libqt5core5a_5.7.1 cannot be installed because libdouble-conversion1 is not installed.
4. Trying to remove libdouble-conversion1v5 (in order to install libdouble-conversion1) fails, because libqt5qml5 depends on libdouble-conversion1v5.

My system might be hozed!
I cannot do a dist-upgrade!

[asifhs 1]

Ok, I force-installed:
libdouble-conversion1
which caused the removal of:
libdouble-conversion1v5
Then I could not run apt-get dist-upgrade. It complained about dependency failures.
I think I resolved this by removing libdouble-conversion1 and reinstalling libdouble-conversion1v5.
I think I cannot use synergy 1.10.0.
But I paid for it! :-(
I would love to get it installed and working!

[asifhs 1]

Ok, I decided to go the compile and install route and it works. Here's what I did:

tclsh ;
uname -a ;
# Host: Linux 4.4.0-130-generic #156-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux
sudo apt-get install libxtst-dev qtbase5-dev libavahi-compat-libdnssd-dev ;
set p synergy-core ;
set d $env(HOME)/Software/Bin/${p} ;
exec >&@stdout git clone https://github.com/symless/${p}.git ;
cd ${p} ;
git checkout -b v1.10.0-stable v1.10.0-stable ;
mkdir build ;
cd build ;
cmake -DCMAKE_INSTALL_PREFIX=${d} .. ;
make ;
make install ;

By-the-way, I compiled and installed it on Ubuntu 16.04 LTS.

Thanks so much.

It has taken me 8 hours to get to this point and get Synergy (1) working again!

I love Synergy, but this is hard work!!

[asifhs 1]

Good to see others getting it to work!
Hope folks will experiment or push the envelop and take it further.

There's a bug on our download page where it sometimes shows Ubuntu users the Debian download.

Please use this instead: https://symless.com/synergy/download/direct?platform=ubuntu&architecture=x64

Let me know if that doesn't work and we can try something else.
