Version: arduino-cli version 0.3.2-alpha.preview
Plafform: RPi3/RPi2B+

Note: This issue is intended to address only the RPi (arm) version. The 64bit version runs fine on Ubuntu 18.04

[cmaglie]

Are you running the cli without any custom config file?

[wjwieland]

@cmaglie
I have the standard .cli-config.hml in ~/$HOME if that is what you mean.
The contents of which are:

proxy_type: auto
sketchbook_path: /home/wjw/Arduino
arduino_data: /home/wjw/.arduino15
board_manager: null

Same behaviour here on my RPi 3:

May you try this build?

This seems to work a lot better:

Pi3:~ $ ./arduino-cli-25-PR91-linuxarm core update-index
Updating index: package_index.json downloaded

Will test further later today, but this specific issue is resolved for me.

[wjwieland]

This fixes the issue on 64 bit machines.
When might this be pushed out to the 32 bit and RPi platforms?
Thanks so much for looking into this!

[OBerghmans]

For me this fixed it on the RPi platform, at least on RPi3

[wjwieland]

I can confirm update-index for both core and lib on the linux 64 and linux ARM now work as expected. For some reason I get 404 - not found error when attempting to retrieve the Linux 32 tar.bz2 file from the code-coverage page 'Build completed' download link, so have not yet tested on my 32 bit system.

Thanks again for the work on this!
