Bug#877481: casacore-data-tai-utc: trigger problem during upgrade from stretch to buster

[Andreas Beckmann]

Followup-For: Bug #877481

Hi,

I think there are more similar problems left. If there are missing
dependencies in stretch, you may have to use Breaks smewhere as well ...

Attached is a new log still showing the issue.
This is from a stretch system with --install-recommends enabled and
libcasa-measures2 instealled.

The failure happens during 
apt-get upgrade
from stretch to buster. The followup comand would have been
apt-get dist-upgrade
The upgrade process runs smooth if there is no separate apt-get upgrade
run first.

Bug#877481: casacore-data-tai-utc: trigger problem during upgrade from stretch to buster

[Ole Streicher]

Control: reassign -1 python3-astropy 2.1.2-4
Control: affects -1 casacore-data-tai-utc

The problem is a missing dependency of python3-astropy from
python3-numpy-abi${ABI}, which needs to be calculated and included in
${python3:Depends}.

Package: casacore-data-tai-utc
Version: 1.1
Severity: serious
Tags: buster sid
User: debian...@lists.debian.org
Usertags: piuparts
Control: affects -1 + libcasa-measures2

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'stretch'.
It installed fine in 'stretch', then the upgrade to 'buster' fails.

The piuparts test was as follows:
* # create stretch chroot with --install-recommends enabled
* apt-get install libcasa-measures2
* # switch sources.list to buster
* apt-get upgrade  # to buster
* # if that hadn't failed the next step would have been apt-get dist-upgrade

Looks like some dependency is insufficiently versioned, allowing a
bad partial upgrade to happen.


cheers,

Andreas
