Hello,

We are using an implementation of a build server which utilizes toaster for=
 build artifact/stage presentation. In order to achieve this we run a main =
instance with nobuild which lives outside of our build environments i.e. ht=
tps://docs.yoctoproject.org/4.3.4/toaster-manual/setup-and-use.html#setting=
-up-toaster-without-a-build-server ( https://docs.yoctoproject.org/4.3.4/to=
aster-manual/setup-and-use.html#setting-up-toaster-without-a-build-server )=
 as we only want the web interface to catch and show our command line build=
s
cd /var/www/toaster/
source poky/oe-init-build-env
source toaster start nobuild
then from our build environments we run a noweb instance i.e. https://docs.=
yoctoproject.org/4.3.4/toaster-manual/setup-and-use.html#setting-up-toaster=
-without-a-web-server
source /projects/project1/poky/oe-init-build-env
source toaster start noweb
bitbake target
source toaster stop
and all is good. This works well where projects as well as the main instanc=
e of poky used to launch the webserver share the same version, say gatesgar=
th.

However, then comes a time where one of the projects moves on to a later ve=
rsion of poky, say scarthgap, and the noweb launch starts having issues. We=
 setup a venv in that particular build env and install all the toaster reqs=
. Starting the noweb instance at this point
$ cd /projects/project2/
$ source poky/oe-init build
$ source venv/bin/activate
$ source toaster start noweb
The system will start.

Did you install mysqlclient?
Failed migrations, halting system start

Any ideas what might be going wrong here? Also, any suggestions of doing th=
is in a way that could save us from compatibility issues when the poky vers=
ion moves?
