Question

I can access my lg web OS server through SFTP, But I want to access the server from terminal in ssh, It will raise the error

ssh -i .ssh/tv43_webos [email protected] -p 9922                                                                                               jwtiyar@ArcJwtiyar
Enter passphrase for key '.ssh/tv43_webos':
PTY allocation request failed on channel 0

mounting and unmounting not working as suggested by some users:

sudo mount devpts /dev/pts -t devpts  

Iam using Archlinux.

You're missing the -T flag:

If an interactive session is requested ssh by default will only request a pseudo-terminal (pty) for interactive sessions when the client has one. The flags -T and -t can be used to override this behaviour.

ssh -i .ssh/tv43_webos [email protected] -p 9922 -T
