I just noticed that after running arduino-cli core update-index, arduino-cli creates 2 folders inside the same folder where the arduino-cli binary is, called worda and wordb.
Is this normal?
And I think it creates the same folders from wherever I run arduino-cli binary. I mean, if I'm inside some project folder and run arduino-cli from there, it will also create the same folders in this folder!
Sorry the delay.
I was having also other issues and I end up deleteing my ~/.arduino15 folder and also the arduino-cli folder. Re-downloaded arduino-cli, restarted a new config init an dnow it seems to be working fine! Can't see these 2 folders anymore!
One other issue I was having was that any time I ran update-index and/or upgrade I could see packages being downloaded and installed over and over again each time!
Anyway, problem, seems to be solved!
