Hi,
Fisrt of all, thank you for using SlapOS platform. The message 'Looking for a free partition' mean that SlapOS Master couldn't allocate your requested instance. The possibles actions and responses for this problem can be found in our FAQ.
About deployment of SlapOS Master, the documentation your are using is outdated, we are updating our developer documentation and we didn't update this documentation yet, please read this documentation for the updated one.
The recommended procedure today to depoy SlapOS Master for development purpose is to request a webrunner then request SlapOS Master inside, this let you easily control your SlapOS Master instance through webrunner. You can follow this documentation to know how to request webrunner on Vifib platform. But you can still to the procedure of SlapOS Master installation in your own computer like your started before.
After you have requested your webrunner, go to "Menu" -> " Open Software Release" then select 'slapos-master' in software folder and open it. You can now click on the green button and inspect the result.
About questions:
1- If you still have the message 'Looking for a free partition' after you have paid the subscription invoice of 2 €, this can mean than your Software Release is not installed into the computer your are trying to use. You can request installation of Software Release from slapconsole with Supply command like in the documentation you are following for SlapOS Master deployment. Make sure that you have used the same computer Id (COMP-XXX) in your supply and request command.
If you compile software release from your own computer, you can also check log in folder /opt/slapos/log/slapos-node-software.log. If your instance is under deployment and is reporting errors, you can check log in : /opt/slapos/log/slapos-node-instance.log
2- Normally the payment validation should not be so long. Please let us know how long it take to validate your payment so we can improve if it's needed. You can also create a tiket in slapos.org / slapos.vifib.com so we will have more information to correctly handle the problem.
3- It's great that you can participate in ERP5 development and deployment, please try above procedure for SlapOS Master deployment and let us know if you have any issue.
