Bug#1133364: apt should ignore 0 epoch when downloading or installing with a version specifier

Package: apt
Version: 3.2.0
Severity: normal

Hi,

According to Debian policy 5.6.12. a zero epoch "may be omitted, in
which case zero is assumed." [0]. Currently this does not work:

$ apt download woff-tools=2009.10.04-2+1.3.1-2
Error: Version '2009.10.04-2+1.3.1-2' for 'woff-tools' was not found

# apt install woff-tools=2009.10.04-2+1.3.1-2
Error: Version '2009.10.04-2+1.3.1-2' for 'woff-tools' was not found

$ apt download woff-tools=0:2009.10.04-2+1.3.1-2
Get:1 https://deb.debian.org/debian unstable/main amd64 woff-tools all 0:2009.10.04-2+1.3.1-2 [3.024 B]

Can you please add support for this? This would fix the code in
debrebuild and allow to reproduce more packages on reproduce.d.n

Thanks!

Jochen
