I have a workstation running under Debian testing (stretch). I need to access it from outside my local network, and due to not having a static public IP nor ability to use full port forwarding, for years I've been using Hamachi to access my machines remotely.

Unfortunately on Debian Stretch I can't seem to be able to install the logmein-hamachi package from logmein labs. There is an unsatisfied dependency - lsb-core, which isn't in the stretch repo anymore.

The logmein-hamachi package is from logmein labs: https://secure.logmein.com/labs/logmein-hamachi_2.1.0.139-1_amd64.deb

This is what happens when I try installing the package in question:

sudo dpkg -i logmein-hamachi_2.1.0.139-1_amd64.deb 
(Reading database ... 177847 files and directories currently installed.)
Preparing to unpack logmein-hamachi_2.1.0.139-1_amd64.deb ...

  Package lsb-core is not installed.

dpkg: error processing package logmein-hamachi (--install):
 dependency problems - leaving unconfigured
Processing triggers for systemd (228-6) ...
Errors were encountered while processing:

Of course I tried installing lsb-core, but it's not in repo anymore (afaik it's been dropped for Debian releases any newer than Jessie):

sudo aptitude install lsb-core
No candidate version found for lsb-core

No packages will be installed, upgraded, or removed.

Has anyone tried to install it or maybe knows how to trick Hamachi into installing and working without it?

The output of dpkg run on the deb is. It looks like a source is not available here.

  • Can you provide more information? The following would be helpful. (a) A link to the deb file in question. If the source deb is available, please provide a link to that too. You might be able to rebuild it on stretch. (b) the exact commands you typed + error messages. Feb 25, 2016 at 10:20
  • I edited the question. Link to the package file + commands + errors are now included.

  • Rebuilding the package yourself with appropriate modifications would probably be your best bet. I don't know anything about this software. Is the source available? If not, manually disassembling the deb, editiing the relevant file to modify runtime dependencies, and then reassembling is also an option, but then of course, the question remains of why lsb-core is a requirement. I suggest you talk to the distributors. They're really the only people who can answer these questions. Feb 25, 2016 at 11:23

It does indeed appear that lsb-core is not currently in stretch. See https://packages.debian.org/search?keywords=lsb-core&searchon=names&suite=all&section=all

Also the changelog says (in the lsb (9.20150826)) entry,

Drop all the LSB compatibility packages besides lsb-release and lsb-base

At this point, your best bet would be as follows.

  1. Talk to the maintainers/developers/distributors about this issue. They may care. (a) I would ask them whether they can provide you the source deb to modify. The answer will probably be no. (b) Whether they can make a deb package for you that will work with the current stretch. (c) Why lsb-core is required.
  2. If you get no joy from them, you could try manually disassembling the deb, editing the relevant file to modify runtime dependencies, and then reassembling. However, of course, the question remains why lsb-core is a requirement.

  • @muru Well, that's a shame. Feb 25, 2016 at 11:55
  • It might be possible to just create an equivs package, or install Jessie's lsb-core package by downloading it directly. Given the contents of lsb-core I'm not sure there's anything there that hamachi would actually need... Feb 25, 2016 at 12:06
  • @StephenKitt Yes, an equivs package would also be a reasonable way to go. Messing around with lsb itself might create problems if other packages depend on a particular version (or version range). Feb 25, 2016 at 14:23
  • @StephenKitt, I tried installing the lsb-core package from Jessie, and it had a lot of unsatisfied dependencies as well. I sent an e-mail to the LogMeIn-Hamachi support, and I'll inform when I get an answer from them. Maybe they'll figure out what's the best remedy for this problem.

This may be a bit late, but "[Hamachi] can now be installed without [the] LSB package."

  • Accepted as this is a solution now.

I contacted LogMeIn and their reply was pretty much that the Hamachi for Linux is a beta and I'm on my own.

I unpacked the .deb package and reviewed the files. I found out that the lsb-core package is needed for installation:

/var/lib/dpkg/info/logmein-hamachi.postinst: 12: /var/lib/dpkg/info/logmein-hamachi.postinst: /usr/lib/lsb/install_initd: not found

and removal:

/var/lib/dpkg/info/logmein-hamachi.prerm: /usr/lib/lsb/remove_initd: not found

of the hamachi client.

I removed the dependency from the control file and the package installed (with the above "not found" errors of course). I had to start the client manually after reboot, but it works fine.
