[Bug 1896084] [NEW] vm does not boot in modern versions of linux

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Hello
First of all, thank you for the excellent work done by the developers in this program. I've been a marionnet user for years now and it's been with me since ubuntu 10.04. In the latest versions of Linux (Debian 10 and Ubuntu 20.04) I have managed to install it but when starting the machines or the routers it gives the message: "A process died unexpectedly". At the suggestion of one of you I have installed the libvdeplug2 package but it does not solve it. I send you the output of the marionnet -d command when trying to run a debian-wheezy machine:

Bug description:
  Hello
  First of all, thank you for the excellent work done by the developers in this program. I've been a marionnet user for years now and it's been with me since ubuntu 10.04. In the latest versions of Linux (Debian 10 and Ubuntu 20.04) I have managed to install it but when starting the machines or the routers it gives the message: "A process died unexpectedly". At the suggestion of one of you I have installed the libvdeplug2 package but it does not solve it. I send you the output of the marionnet -d command when trying to run a debian-wheezy machine:
