Warning Report: Multiple deprecated function warnings in libssh usage

During compilation of the project, a significant number of warnings are generated due to the usage of deprecated functions from the libssh library. These deprecated APIs include functions such as publickey_from_file, privatekey_from_file, privatekey_free, ssh_channel_get_exit_status, ssh_channel_select, ssh_scp_free, ssh_scp_close, ssh_scp_push_file64, ssh_scp_accept_request, sftp_server_init, among others.

The warnings appear mostly in the files:

• 3rd-party/libssh/libssh/src/legacy.c
• 3rd-party/libssh/libssh/src/scp.c
• src/sshfs_mount/sftp_server.cpp
• src/ssh/ssh_client.cpp

Hi @alexio-dev

Yes, we have known about this, just haven't gotten around to doing something about it.

Hi can I solve this?

I like to practice my programing skills

[sharder996]

Hi @Gere321123, I would start by looking at the relevant files in Multipass (you can ignore the files under 3rd-party as those are external dependencies) to see how these functions are used and then consult the libssh (here and here) documentation for new supported functions.

Hi! Any news on this one? I also want to help.

[Gere321123]

I'm right now a little bit busy so if you want @MadalinGOIAN you can take it.
