From 2f88881c933d957885fec6ac565b553e4c7d9a3d Mon Sep 17 00:00:00 2001 From: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> Date: Wed, 23 Jan 2019 11:43:04 +0000 Subject: debian package: symlink to python-3.X (#4433) In the debian package, make the virtualenv symlink python to /usr/bin/python3.X rather than /usr/bin/python3. Also make sure we depend on the right python3.x package. This might help a bit with subtle failures when people install a package from the wrong distro (https://github.com/matrix-org/synapse/issues/4431). --- debian/build_virtualenv | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) (limited to 'debian/build_virtualenv') diff --git a/debian/build_virtualenv b/debian/build_virtualenv index 83346c40f1..8b51b9e074 100755 --- a/debian/build_virtualenv +++ b/debian/build_virtualenv @@ -6,7 +6,16 @@ set -e export DH_VIRTUALENV_INSTALL_ROOT=/opt/venvs -SNAKE=/usr/bin/python3 + +# make sure that the virtualenv links to the specific version of python, by +# dereferencing the python3 symlink. +# +# Otherwise, if somebody tries to install (say) the stretch package on buster, +# they will get a confusing error about "No module named 'synapse'", because +# python won't look in the right directory.
