Comment 5 for bug 1783019

@halibuth - regarding the issue on Windows:
Please see the FAQ at [1] and see if it helps you solve the problem.

@jpmilton - regarding the issue on Fedora:
It seems the default "python" on your system is Python 3, which is not (yet) compatible with Inkscape and obviously will not be able to make use of python2-lxml. You can manually force the Python interpreter to "python2", see [2]. You might also consider letting packagers for Fedora know about this issue.

@abdelhaksam - regarding the issue on Antergos Linux:
Probably the same cause as on Fedora, so I suggest the same steps.

@all: For system-specific support requests like these it's usually better to ask on the inkscape-user mailing list or better yet to use the support channels fo your Linux distro. (Especially in cases like this, where similar issues can have very different causes that might not even be addressable by Inkscape developers themselves).
