Hi,

I had to skip a part of the test suite of the uncalled package.  You
can see the according commit with verbose documentation here:

https://salsa.debian.org/med-team/uncalled/-/commit/607d1ec0f8bbc3f2e9f755000705b1325c87c769

It would be great if we could run the full test suite[1] including the
command

   uncalled map index/example_ref fast5_filename.txt

If you think there is no chance to support this please tag the bug
wontfix and let me know.  Most probably this will affect more packages
than just uncalled.

Kind regards
   Andreas.

Please be more specific. A quick check using h5dump shows that the file
is correctly read by HDF5 2.2.0.
