SOLVED: unison 2.48 breaks unison-all

I thought I was getting near finished  in a new install of Debian Testing on a new computer   I was so surprised over a year ago to see with the addition of unison-all that unison could now talk to various versions.  Unstable could talk to stable.  But not anymore,  the bump to unison 2.48 shattered this belief.

It stems from way upstream in Unison and Ocaml sources

Has anyone had any luck using dpkg or backports to get unison from stable or back-ports into a testing version of Debian lately?  I have tried a little with dpkg to install old binaries from stable.  No luck yet.   Yes I will read up on apt-pin, been awhile since I have used.

Unison 2.48-3 breaks "unison-all".   

https://bugs.debian.org/cgi-bin/bugrepo … bug=810212   Testing to Jessie does not work

Also - pointing to the upstream problems  https://bugs.debian.org/cgi-bin/bugrepo … bug=802919   

Sigh,  I am far from an expert in compiling.  But once I did get ocaml and unison compiled into .ipkg form for ffp on an arm dns-323 - and well, I am not even considering that again. ((BTW if anyone is capable of doing this - ffp-funpkg and Alt-F would love .ipkg's of ocaml and unison for 0.40) My deep appreciation and sympathy go out to the Debian OCAML maintainers, it is a difficult task.  PM me if you want old binaries for ocaml and unison for a DNS-323.   

There are other ways for me to fix this, but Peace out.

You could try forwardporting the application from stable -- the process is exactly the same as backporting:

Thanks,  I went with plan B  First I downloaded the .deb from stable - then

dpkg -i unison_2.40.102-2_amd64.deb 
apt-cache policy unison
echo unison hold|dpkg --set-selections

The mame looks quit interesting, using an arcade emulator to go beyond it's intended goals.  That is a hallmark of excellent programming.  But after battling with kvm-qemu and the the surrender to virutalbox and the vicissitudes of Windows 7 wherever it resides, well next goal is to figure out keybndings keybindings for xmw4 in an lxqt environment. 

Again, thanks.

It can be "safer" to use gdebi to install foreign .deb packages as that will refuse if the action will break the dependency chain whereas dpkg(1) offers no such restraint.
