Package: postfix Version: 3.1.4-7 Severity: minor Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? trying to use : /usr/sbin/postfix-add-policy * What exactly did you do (or not do) that was effective (or ineffective)? run the command. * What was the outcome of this action? postfix-add-policy: /usr/bin/python3: bad interpreter: No such file or directory * What outcome did you expect instead? policy to be added in master.cf The following happen and how to detect. Basic stretch server installation. ( standard tools + ssh server ) Installed postfix. when running the command : postfix-add-policy usename path_to_file resulted in : /usr/bin/python3: bad interpreter: No such file or directory and nothing was added in master.cf 2 possible fixed, and correct solution is a depend problem fix. fix1 : edit the file /usr/sbin/postfix-add-policy, change #!/usr/bin/python3 to #!/usr/bin/python I installed reportbug. ( and all its dependecies, one of these fixed the problem also. i changed the #!/usr/bin/python back to #!/usr/bin/python3 did run the command again : postfix-add-policy usename path_to_file Now it worked fine. The following (python) packages where installed by reportbug, one of these fixed my problem. dh-python libpython3.5-minimal libpython3.5-stdlib libpython3-stdlib python3 python3.5 python3.5-minimal python3-apt python3-chardet python3-debian python3-debianbts python3-httplib2 python3-minimal python3-pkg-resources python3-pycurl python3-pysimplesoap python3-reportbug python3-requests python3-six python3-urllib3 python-apt-common -- System Information: Debian Release: 9.1 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-3-amd64 (SMP w/12 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages postfix depends on: ii adduser 3.115 ii cpio 2.11+dfsg-6 ii debconf [debconf-2.0] 1.5.61 ii dpkg 1.18.24 ii init-system-helpers 1.48 ii libc6 2.24-11+deb9u1 ii libdb5.3 5.3.28-12+b1 ii libicu57 57.1-6 ii libsasl2-2 2.1.27~101-g0780600+dfsg-3 ii libssl1.1 1.1.0f-3 ii lsb-base 9.20161125 ii netbase 5.4 ii postfix-sqlite 3.1.4-7 ii ssl-cert 1.0.39 Versions of packages postfix recommends: ii python3 3.5.3-1 Versions of packages postfix suggests: pn dovecot-common <none> ii libsasl2-modules 2.1.27~101-g0780600+dfsg-3 pn postfix-cdb <none> pn postfix-doc <none> ii postfix-ldap 3.1.4-7 pn postfix-lmdb <none> ii postfix-mysql 3.1.4-7 ii postfix-pcre 3.1.4-7 pn postfix-pgsql <none> pn procmail <none> pn resolvconf <none> ii s-nail [mail-reader] 14.8.16-1 pn sasl2-bin <none> pn ufw <none> -- debconf information excluded
