Hi All,

I have figured out why the fuse mount stopped working with borgbackup in Core=
 Update 173. (Bug#13076)


python3-trio was updated when python was updated to 3.10.8 and python3-trio i=
s required by python3-pyfuse3. However the python3-trio update also added a n=
ew dependency - python3-exceptiongroup which then requires python3-flit_scm f=
or the build of python3-exceptiongroup.


Both python3-exceptiongroup and python3-flit_scm use pyproject.toml, however =
python3-pyproject2setuppy fails with trying to build python3-flit_scm as it d=
oes not understand the backend definition in the pyproject.toml file.

The error message is :-

 =C2=A0=C2=A0=C2=A0 File "/usr/lib/python3.10/site-packages/pyproject2setuppy=
/__main__.py", line 50, in main
 =C2=A0=C2=A0=C2=A0 raise NotImplementedError(
 =C2=A0=C2=A0=C2=A0 NotImplementedError: Build backend flit_scm:buildapi unkn=
own


pyproject2setuppy is now marked as DEFUNCT due to the number of special cases=
 in the pyproject.toml file that needed lots of work each time to update pypr=
oject2setuppy to work again.


Does anyone have any idea how I should build flit_scm and exceptiongroup with=
out using pyproject2setuppy.

I have done some searching but could not find anything that I could either un=
derstand or that did not require internet access to download all required dep=
endencies.


Regards,

Adolf.
