We have put our efforts in ensuring that Netkit could work flawlessly on most Linux distributions. However, in the presence of some particular configurations, Netkit may exhibit malfunctions or be unable to start. Based on our tests and on precious reports by Netkit users, we maintain the following compatibility list.

We encourage users who are experiencing trouble with Netkit to report their issues, so that we can attempt to provide a fix and thus enrich the compatibility list. Reports of any successful experience with Netkit are of course likewise appreciated!

Before reporting any problem, please have a look at the list below and check whether there already exist remedies for the distribution under consideration or support for it is simply broken at present.

The status is classified by distribution, as follows:

 update-alternatives --config sh;
  • link /bin/sh to /bin/bash; as root: 
 ln -fs /bin/bash /bin/sh;
  • replace every occurrence of #!/bin/sh in the Netkit scripts with #!/bin/bash.
