[FAS3] CAPTCHA image broken

[ryanlerch]

I an unable to create an account on my FAS3 test instance, because when i get to the final screen of the create account process, the CAPTCHA image is not displaying.

This might be an dependency issue. Could I have the log when going to registration's page?

[ryanlerch]

This is what is returned when going to the reg page: https://gist.github.com/ryanlerch/2ae7746c926fa661696d

[laxathom]

Could you give me the OS version you're trying to test this on and PIL package version as well?

[ryanlerch]

No longer getting the deprecated exception, but it is still not working. Now i get the following error:

This is running on Fedora 25, with the following version of Pillow (as per pip freeze): Pillow==3.4.2

[skrzepto]

hmm odd it seems to work on F24 and Pillow==3.4.2 for me if you are referring to the captcha for adding numbers?

Is this replicated in the vagrant file you created I can try to reproduce the error on my machine

[ryanlerch]

I get the error when trying to view "/register". And on the thrid page of that form, the CAPTCHA is not displaying.

Yes, the Vagrant setup is where i am hitting this issue.

[ryanlerch]

Okies! I have figured it out!

I missed the following error:

2016-12-15 05:56:05,912 ERROR [waitress:2784][root:captcha][__jpeg_generator__:108] Unable to read from Image Font: cannot open resource

And it turns out that development.ini defines liberation-mono as the font to use for the CAPTCHA, and i didnt have it installed on my development machine.

So, after a sudo dnf install liberation-mono-fonts, my CAPTCHAs are now appearing.
