Setup: Debian 9.3 ARMv7 I have followed the documentation in installing with python3. The documentation is hard to understand since so this issue may just be a misconfiguration. No one is online on the IRC channel. I have successfully run ./gmg/dbupdate. Then tested using lazyserver all ok. But when I upload files using the apache wsgi interface based on the wiki it fails to work. The /var/lib/mediagoblin I changed to my partition of var custom. Here are what I did:

$ sudo useradd -c "GNU Mediagoblin..." -d /mnt/myvar/mediagoblin -m -r -g www-data mediagoblin $ sugo groupadd mediagoblin && sudo usermod --append -G mediagoblin mediagoblin $ sudo usermod --append -G myvargroup mediagoblin $ sudo mkdir -p /srv/mediagoblin && sudo chown -hR mediagoblin:www-data /srv/mediagoblin $ sudo su mediagoblin -s /bin/bash && cd /srv/mediagoblin $ git clone ​git://git.savannah.gnu.org/mediagoblin.git -b stable $ cd mediagoblin $ pwd $ /srv/mediagoblin/mediagoblin $ git submodule init && git submodule update $ ./bootstrap.sh $ ./configure --with-python3 $ make $ mkdir user_dev && chmod 750 user_dev $ ./bin/easy_install flup $ cp -av mediagoblin.ini mediagoblin_local.ini && cp -av paste.ini paste_local.ini

I have reviewed all config and tickets but still no fix. I used python3, python2 appears to not work for me, also I use nginx, debian 9.3.

git cloned master a few minutes ago.

setup.py depends on wtforms without specifying version. So I used 1.0.1, the most common wtforms version found (e.g. on Ubuntu 14.04 released 4 months ago).

Error follows.

$ gmg dbupdate

On wtforms 1.0.1 there is only wtforms.validators.Required.

Either change code to stay with wtforms 1.0.1 (most commonly found),

or be explicit that this version is not acceptable in setup.py - wtforms 2 seems have this class.
