@abr4xas thanks for the report. will have a look & fix ASAP.
Update
@abr4xas are you using virtualenv to download courses? facing this error in this particular course or in any course?

[abr4xas]

@r0oth3x49 nop, i'm using Ubuntu 16.04.3 LTS. With any course.

@abr4xas thanks for explanation & using this script i will test this script on Ubuntu 16.04.3 LTS against some free courses will add a fix ASAP.

[r0oth3x49]

@abr4xas i have downloaded Ubuntu 16.04.3 LTS 64-bit and tested against a free course in my account it worked for me i cannot reproduce the error. have a look below.

It is strange, I had tried with 3 different courses and always the same error...

[r0oth3x49]

@abr4xas it took two days to download the latest available ubuntu-16.04.3-desktop-amd64. did you installed all the requirements? try installing requests[security] or try to download using virtualenv.
or try with python3 may be it works for you. and one more solution try to give all permissions to all files and folders in udemy-dl

@abr4xas one of my friend face the same problem. but according to him that was a human error, & i have shown you the image above tested on latest ubuntu on VMware which works fine so i 'm closing this error and will w8 for more similar reports.
