Sphinx 2.3 Installation fails on add interface step

Good day.

I am trying to install Sphinx 2.3 to my Ubuntu 18.04 environment. I have access to the repositories and so it finds the package just fine, but when I install it, it fails when creating the virtual ethernet devices in /etc/network/interfaces.

The following packages will be upgraded:
1 upgraded, 0 newly installed, 0 to remove and 8 not upgraded.
Need to get 0 B/227 MB of archives.
After this operation, 557 MB of additional disk space will be used.

add "iface fd_vethXXX inet manual" to /etc/network/interfaces

Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

When I inspect /etc/network/interfaces afterwards it has 256 veth interfaces defined. I tried removing all of those interfaces manually and performing the install again, but it fails int he same way. I currently have Sphinx 1.2 installed, so it is possible that is playing into the issue.

iface fd_veth0 inet manual
iface fd_veth255 inet manual

Has anyone else encountered this? I was contemplating removing Sphinx 1.2 and trying to install rather than upgrade, but I thought I would test the waters here first.



You can’t have multiple versions installed. Their files are in the same /opt/parrot-sphinx directory.

Thanks @ocrave. I will try to uninstall the older version first.


sudo apt remove parrot-sphinx
sudo apt install parrot-sphinx

did seem to work. Thanks @ocrave. It might be beneficial to add some mention of this in the Installation section of the Sphinx 2.3 documentation for others who may be upgrading.
