When I try to connect to my office computer with tramp: C-x f "/ssh:office:" it shows me the message: "Found remote shell prompt on" and then completely hangs. I have to terminate with C-g, if I hit enter the emacs session dies completely. Connecting with "ssh" works fine.

These are the complete error messages:

This is the debug tramp/ssh buffer:

According to the traces, Tramp sends the following command after it has connected the remote host:

exec env ENV='' HISTFILE=/dev/null PROMPT_COMMAND='' PS1=\#\$\  PS2='' PS3='' /bin/sh

The output is

[Keexec env ENV='' HISTFILE=/dev/null PROMP 
[KT
T_COMMAND='' PS1=\#\$\  PS2='' PS3='' /bin/sh 

]0;matias@matias-HP-ProDesk-600-G1-TWR: exec env ENV='' HISTFILE=/dev/null PROMPT_COMMAND='' PS1=\#\$\  PS2='' PS3='' /bin/sh #$ 

Looks, like there are strange prompt settings. Check the Tramp manual for techniques how to suppress those settings.
