Package: matrix-sydent Version: 2.5.1-1.1 Severity: serious User: jo...@debian.org Usertags: adduserpurge Control: tag -1 + patch
Hi, the packages passwd and adduser are not part of the Essential:yes set. According to policy §7.2 maintainer scripts cannot assume them being installed when purging a package. If one tries to remove this package without adduser (which depends on passwd) installed, one gets: --%<------------------------------------------------------------------------- Purging configuration files for matrix-sydent (2.5.1-1.1) ... /var/lib/dpkg/info/matrix-sydent.postrm: 28: deluser: not found dpkg: error processing package matrix-sydent (--purge): installed matrix-sydent package post-removal script subprocess returned error exit status 127 Errors were encountered while processing: matrix-sydent -->%------------------------------------------------------------------------- There is ongoing discussion how to handle system users on package removal, see https://bugs.debian.org/621833 For a discussion about use of adduser during purge, see #1035654. To work around this problem, at least 125 source packages [codesearch] simply ignore failures of calling the passwd or adduser tools during purge. The following patch should fix this package by doing the same: --%<------------------------------------------------------------------------- diff -Nru matrix-sydent-2.5.1/debian/postrm matrix-sydent-2.5.1/debian/postrm --- matrix-sydent-2.5.1/debian/postrm 2021-06-01 21:17:05.000000000 +0200 +++ matrix-sydent-2.5.1/debian/postrm 2023-05-10 07:46:13.000000000 +0200 @@ -25,7 +25,7 @@ dpkg-statoverride --force-all --quiet --remove "${DIR}" done - getent passwd "${USER}" >/dev/null && deluser "${USER}" + getent passwd "${USER}" >/dev/null && deluser "${USER}" || true rm -f /var/lib/${NAME}/* if [ -d /var/lib/${NAME} ]; then -->%------------------------------------------------------------------------- If you prefer I can fix this via an NMU.
