As per the Debian Python Policy (I can't find a similarly thorough document for Ubuntu), > The preferred specification for the Python interpreter is /usr/bin/python or /usr/bin/pythonX.Y. This ensures that a Debian installation of python is used and all dependencies on additional python modules are met. > Maintainers should not override the Debian Python interpreter using /usr/bin/env python or /usr/bin/env pythonX.Y. This is not advisable as it bypasses Debian's dependency checking and makes the package vulnerable to incomplete local installations of python. I think this is reasonable, and also supported by the majority of the Python scripts in my /usr/bin directory. This also has potential security implications, i.e. someone with only user-level access could override the system Python in a user's ~/.bash_profile and install a malicious version of certain package dependencies. dwf@barricade:~$ lsb_release -rd Description: Ubuntu 11.04 Release: 11.04 dwf@barricade:~$ grep '#!/usr/bin/env python' /usr/bin/* /usr/sbin/* |cut -d ':' -f 1|xargs dpkg -S gconf2: /usr/bin/gsettings-schema-convert mercurial-common: /usr/bin/hg-ssh hplip: /usr/bin/hp-align hplip: /usr/bin/hp-check hplip: /usr/bin/hp-clean hplip: /usr/bin/hp-colorcal hplip: /usr/bin/hp-firmware hplip: /usr/bin/hp-hpdio hplip: /usr/bin/hp-info hplip: /usr/bin/hp-levels hplip: /usr/bin/hp-makeuri hplip: /usr/bin/hp-pkservice hplip: /usr/bin/hp-plugin hplip: /usr/bin/hp-probe hplip: /usr/bin/hp-query hplip: /usr/bin/hp-scan hplip: /usr/bin/hp-setup hplip: /usr/bin/hp-testpage hplip: /usr/bin/hp-timedate hplip: /usr/bin/hp-unload gnome-applets: /usr/bin/invest-chart pitivi: /usr/bin/pitivi libpurple-bin: /usr/bin/purple-remote libpurple-bin: /usr/bin/purple-url-handler hplip: /usr/sbin/hpssd dwf@barricade:~$ grep '#!/usr/bin/env python' /usr/bin/* /usr/sbin/* |cut -d ':' -f 1 |xargs dpkg -S |cut -d':' -f 1|xargs apt-cache policy gconf2: Installed: 2.32.2-0ubuntu2 Candidate: 2.32.2-0ubuntu2 Version table: *** 2.32.2-0ubuntu2 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/main i386 Packages 100 /var/lib/dpkg/status hplip: Installed: 3.11.1-2ubuntu2 Candidate: 3.11.1-2ubuntu2 Version table: *** 3.11.1-2ubuntu2 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/main i386 Packages 100 /var/lib/dpkg/status gnome-applets: Installed: 2.32.1.1-0ubuntu5 Candidate: 2.32.1.1-0ubuntu5 Version table: *** 2.32.1.1-0ubuntu5 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/main i386 Packages 100 /var/lib/dpkg/status libpurple-bin: Installed: 1:2.7.11-1ubuntu2.1 Candidate: 1:2.7.11-1ubuntu2.1 Version table: *** 1:2.7.11-1ubuntu2.1 0 500 http://security.ubuntu.com/ubuntu/ natty-security/main i386 Packages 100 /var/lib/dpkg/status 1:2.7.11-1ubuntu2 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/main i386 Packages pitivi: Installed: 0.13.5-1ubuntu4 Candidate: 0.13.5-1ubuntu4 Version table: *** 0.13.5-1ubuntu4 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/main i386 Packages 100 /var/lib/dpkg/status mercurial-common: Installed: 1.7.5-1ubuntu1 Candidate: 1.7.5-1ubuntu1 Version table: *** 1.7.5-1ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ natty/universe i386 Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/912625/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
