Source: gmp-ecm Version: 6.4.4+ds-5 Severity: normal One has for libecm0 6.4.4+ds-5:
Recommends: gmp-ecm (= 6.4.4+ds-5) and for libecm1 7.0+ds-1: Recommends: gmp-ecm (= 7.0+ds-1) i.e. each time with an exact version. According to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=819636#10 this is a bad idea. BTW, is there any reason why one has a "Recommends"? -- System Information: Debian Release: stretch/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.4.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=POSIX, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) -- no debconf information
