Hi @pfsmorigo,
I tried / examined the suggested interfaces, but they don’t allow the access that curl needs. I.e. access to non-mapped /tmp directory. For example to have the output being piped, or just that an installer script writes it’s data there.
And also arbitrary access to $USER directory, as there are also installers using curl, that write to ~/.* files such as the above mentioned npm script.
I saw that there once was talk about a ‘classic’ interface, that sounds like a solutions, but I think it does not exists.
FYI I also started a thread to get a separation between a confined and a non-confined version, see New track (classic) request for the curl snap
