Bug#852305: depends on non existing package libblosc1

[Martin Steigerwald]

Package: python-bcolz
Version: 1.1.0+ds1-2
Severity: serious

Dear Maintainer,

on searching what to install to make

[…]/pkg-fio> tools/hist/fiologparser_hist.py
Traceback (most recent call last):
  File "tools/hist/fiologparser_hist.py", line 18, in <module>
    import pandas
ImportError: No module named pandas

work, I came across python-bcolz.

Yet this is not installable:

[…]~> LANG=C sudo apt install python-bcolz

The following information may help to resolve the situation:

The following packages have unmet dependencies:

                Recommends: python-numexpr but it is not installable
E: Unable to correct problems, you have held broken packages.


[…]~> LANG=C apt-cache policy libblosc1
libblosc1:

  Candidate: (none)

I see no bcolz related upload in 2017, so this issue may be there for quite
some time already.

Thanks,
Martin

This is crap. This is unstable with *some* packages from experimental. It does
certainly not prefer experimental.
