Package: zlib1g Version: 1:1.3.dfsg-2 Severity: serious Hi,
I didn't investigate this further yet but filing this as RC as it is easy to reproduce and it's easy to find out that only zlib1g changed using debbisect. Downgrading to zlib1g 1:1.2.13.dfsg-3 makes the problem go away. Steps to reproduce: $ mmdebstrap --include=tex-common,texlive-base unstable /dev/null Processing triggers for tex-common (6.18) ... Running updmap-sys. This may take some time... done. Running mktexlsr /var/lib/texmf ... done. Building format(s) --all. This may take some time... fmtutil failed. Output has been stored in /tmp/fmtutil.tcAsaQVq Please include this file if you report a bug. dpkg: error processing package tex-common (--configure): installed tex-common package post-installation script subprocess returned error exit status 1 Errors were encountered while processing: tex-common E: Sub-process env returned an error code (1)
