PyWPS quickstart not working

[kalxas]

The quickstarts needs an update for the recent stable version.

[tomkralidis]

Can we downgrade PyWPS to the previous 3.2.x release and milestone for the next LiveDVD release? 4.0 is a rewrite/redesign and we'll need some time to update.

[kalxas]

Downgrading to 3.x would require extra work on the ppa side. Also, having a PyWPS 4.x marked as stable and not included in OSGeo-Live would reflect bad to both projects. We try to include latest stable releases when possible/available.

In any case, the quickstart is very basic and requires a lot of improvement in order to be on par with the other applications on the disk, so downgrading would not actually solve the problem, just the missing service part.

[kalxas]

Looks like we will need to downgrade the package in the ppa.

PyWPS downgraded to 3.2.5.

4.0.0 back to staging area:

After switching back to PyWPS 3.2.5, the quickstart leads to this error:

I guess we will need to revert this commit too?

[jachym]

@kalxas, not sure - looks fine

What are the steps I need to take, in order to test the just the PyWPS installation?

[kalxas]

Hi Jachym,

Have you tried running the quickstart in OSGeo-Live 10.5?

[kalxas]

Ticket retargeted after milestone closed

[kalxas]

PyWPS has been retired from OSGeo-Live 11.0 due to this issue.

[tomkralidis]

kalxas: we would like to re-integrate PyWPS (4) into OSGeo-Live. Can/should we use pip to install PyWPS 4? Or UbuntuGIS? What is PyWPS 4 status on UbuntuGIS?

[kalxas]

Please use this as a starting point:

​https://github.com/OSGeo/OSGeoLive/blob/master/bin/retired/install_pywps.sh

We are using debian packages for installing into OSGeo-Live environments, and PyWPS is already in our ppa.

​https://launchpad.net/~osgeolive/+archive/ubuntu/nightly/+packages

Actually, PyWPS is also available in the release ppa of OSGeo-Live 11.0, so it is one apt-get install away from 11.0 RC1 environment.
