Hi intrigeri, thanks for picking up the discussion about mat/mat2 in Buster!

There's still a chance to get it in: if we craft a patch for nautilus-python that introduces a new package python3-nautilus which is co-installable (and doesn't conflict) with python-nautilus, then the nautilus-python maintainer already said that he would consider to accept it in time for Buster. [1] That basically means that we have to copy libpython-nautilus.c to libpython3-nautilus.c, introduce a new extension include path for it (probably /usr/share/python3-nautilus/extensions/) and patch the build system to build libpython-nautilus.c only for python2 and libpython3-nautilus.c only for python3. Unfortunately I'm unsure whether I find time to work on such a patch within the next week (which probably would be necessary to get the package into the archive in time, since it has to pass NEW). If anybody wants to pick up the work, here's my related PR (which doesn't do what I explained above yet, but should be a starting point): https://salsa.debian.org/gnome-team/nautilus-python/merge_requests/1 In mat2, all we would have to do is install the nautilus extension to the special include path (/usr/share/python3-nautilus/extensions/) instead of the default one. [1] In any case, this would be an intermediate solution for Buster. After buster, the Gnome team plans to start the proper transition from python-nautilus to python3-nautilus, effectively making all packages that don't work with python3-nautilus release-critical. > So it's time to think about contingency > plans here. > > To me this boils down to this question: do we feel more comfortable > with: > > a) including mat v1 in Buster (so less technical can use its GUI, > even though its Nautilus extension was broken last time I tried), > in addition to v2 > > or > > b) only including mat v2, without any GUI at all (and then add > Breaks+Replace, get mat v1 removed from testing, and add > transitional package if there's enough time to go through NEW). > > ? > > I'm personally very uncomfortable with both options :/ > But I'm leaning towards not including software when its author > says it's unsupported and has known (security relevant) issues. I totally agree here. I think that we should file a RM bugreport for mat v1 *now* and introduce a transitional package in mat2 regardless whether we get the nautilus extension for mat2 working in time for Buster. > Other data points & ideas: > > - Given the python-nautilus issue essentially requires a transition, > I doubt we'll find some way to provide desktop integration for mat2 > via buster-backports.

I think the better solution would be to get a working python3-nautilus into Buster, which *is* possible.
