[Pkg-emacsen-addons] Bug#924295: elpa-ibuffer-projectile: fails to upgrade from stretch: ibuffer-projectile.el:51:1:Error: Cannot open load file: No such file or directory, dash

[Andreas Beckmann]

Package: elpa-ibuffer-projectile
Version: 0.2-2
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

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.

This test had --install-recommends enabled (but I can also reproduce it
without). This happened during the 'apt-get upgrade' phase of a two-stage
upgrade (apt-get upgrade && apt-get dist-upgrade).

>From the attached log (scroll to the bottom...):

If you need debug information from the chroot after the failure,
please let me know what you need and how to obtain it.


cheers,
