Expected behavior

backports.csv should be installed. I had to do modify scripts/modoboa.py and add backports.csv to the packages list variable.

I have this bug since a few days, since I saw 1.10.4 was released.

unfortunately the quick fix (ff2bf9994) is not enough for me 😦 the installer spits out a few “ImportError: No module named backports” just like in the original report, and i get “502 Bad Gateway” after a fresh install, just like other people (#208, #206)

i had to resort to monkey-patching the modoboa-installer to fetch modoboa at commit f604aacb61b0

stil, the compilation would fail with a fresh debian 9.3, at the point of compiling lxml from source, due to missing source dependencies (libssl1.0-dev libz-dev)

so right now, i got it working with the following steps (starting with pristine debian 9.3)

sudo apt install git
sudo apt install libssl1.0-dev libz-dev # needed to compile modoboa dependencies from source
sudo git clone https://github.com/modoboa/modoboa-installer /opt/modoboa-installer
sudo sed -i 's|modoboa_package = "modoboa"|modoboa_package = "git+https://github.com/modoboa/modoboa.git@f604aacb61b0b1383bcb5c10943ae2a15f46f93e#egg=modoboa"|'  /opt/modoboa-installer/modoboa_installer/scripts/modoboa.py
sudo /usr/bin/python /opt/modoboa-installer/run.py domain.tld

this will result in a working instance of modoboa==1.10.5.dev8+gf604aacb instead of modoboa 1.10.4 (current latest release), good enough until a proper 1.10.5 release is made 😃

Should work now, I’ve added a quick fix to the installer.
