Source: spectral-cube Version: 0.4.5-1 Severity: serious
Astropy was recently updated to support the new version of wcslib. Unfortunately this fix is being blocked from migrating to testing by an autopkgtest failure in spectral-cube, this is happening in both in migration tests and in plain unstable tests. migration test: https://ci.debian.net/data/autopkgtest/testing/amd64/s/spectral-cube/4375843/log.gz plain unstable test: https://ci.debian.net/data/autopkgtest/unstable/amd64/s/spectral-cube/4382183/log.gz

This seems similar to a testsuite failure that happened in astropy when the inital attempt was made to rebuild it for 7.1 ( https://buildd.debian.org/status/fetch.php?pkg=astropy&arch=amd64&ver=4.0-3%2Bb1&stamp=1582194992&raw=0 ) , said testsuite failure was apparently fixed by https://salsa.debian.org/debian-astro-team/astropy/-/commit/a7a71b323d66984dfc482ea95779e26018fc2cec . Perhaps a similar fix is needed in the spectral-cube tests?
