At the same time, it would be great to have the meaning of checks included in the report.md file. Made a comment on this here

@vv-monsalve, I initially thought this ERROR would be in a PR to the google/fonts repo, but I could not find a Gupter PR there.

Then I cloned https://github.com/vv-monsalve/GUPTER.git and tried to run the latest fontbakery (form git master) on the bold ttf from the FONTS/TTF/ directory. FontBakery passes the check:

Please let me know where I can find files that cause the ERROR.

I ran the FB cheks on my local files that are up to date with my master branch of the upstream repo, I didn't change anything on them, so this is more strange to me now.

I did this on this project actually because I wanted to test the upgrade of Fontbakery on an already proved working job. Before it, I tried to upgrade it in another project, but even though I received the "successfully installed 0.7.24" after three attempts, it remained in 0.7.22. It only got updated after I delete the venv and reinstall the gftools.
It had not happened to me before when updating Fontbakery btw.

Link to a copy of my local Gupter folder. On FONTS/TTF, you can find the resulted folders of the two last QA processes performed and a .txt file with the terminal output, so you can check if I did something wrong.

@vv-monsalve, thanks for the feedback!

@vv-monsalve, I have the impression that you have python 2.7 in your virtual environment. Please delete your venv and create a new one using python 3:

virtualenv venv -ppython3

then install fontbakery and try to run the check agains Gupter again and let me know if that solves the issue.

[vv-monsalve]

@felipesanches The venv was built on python 3.6.
Nevertheless, I confirmed it and replicated the process and got the same three Errors. New report.md and terminal output here

[felipesanches]

oh, ok! So maybe you had an older venv folder with py2 in that ZIP file.

Anyway... I'll keep trying to replicate the bug. Thanks for sending more files. I'll look them up now.

[vv-monsalve]

Sure, no problem. I gave it a quick look and didn't see python 2.7, strange. I hope the new files are of any help!

[vv-monsalve]

It seems like this was caused by conflicts between python versions indeed. After checking this locally with @m4rc1e I created a new venv with selected python 3.7 and everything worked ok with FB.
Closing this here :)
