Unable to upload sketch for ESP8266 due to some elf2bin.py error

[BenniKain]

Hello,
i am trying for hours to get a sensor sending data over wifi to my flask server.
however due to some reason of esp82 error link below i cannot upload the sketch.

it worked 2 times in 4 hours for me seemingly random.

if anyone could help me i d be very thankful

I just tried this 5 times in a row, and it builds fine for a wemos D1 r2 mini.
If your problem is random, and only you seem to be affected, I suggest doing a fresh install from scratch, and make sure you have only one core installed when testing.
Also, my own personal view is that I only trust the IDE downloaded from the Arduino site.
Also, you might want to check whether you have some other Python installed.
Closing due to can't reproduce.

I am having the same problem. Did you figure out what is causing this?

[anilsoni85]

I encountered same issue consistently on Windows 10 and I fixed it by adding reattempt logic in get_segment_size_addr function of elf2bin.py.

Citrix Workspace was causing the issue. I updated Citrix and problem gone!

[kah731]

I have a recent version of Citrix Workspace - hoping to not have to update/remove.

I reinstalled the latest version of python (python-3.11.1-amd64.exe), and that fixed it.
I also let python install the fix to allow longer paths.

[panakos]

I tried that as well but didn't work for me. Citrix update to the latest fixed it

[kah731]

Thanks - somehow it broke again - will try Citrix fix now

[bonfix]

Updated python, didn't work, had to uninstall citrix.
