Shells not detected?

[Godestiny]

Hello,
Someone can help me? I'm trying to switch from sh shell to dash to install a framework.
Dash is present in my /bin directory but when I type:
chsh -l
The shells list fail to show up.
Even with:
su -s dash
I get "Cannot execute dash: No such file or directory"...
Also when I install my famework, I get this error message:
The installer has detected that your system uses the dash shell
as /bin/sh. This shell is not supported by the installer.
You can work around this problem by changing /bin/sh to be a
symbolic link to a supported shell such as bash.
For example, on Ubuntu systems, execute this shell command:
% sudo dpkg-reconfigure -plow dash
Install as /bin/sh? No
Please refer to the Getting Started guide for more information,
or contact CodeSourcery Support for assistance.
So I tried to use:
sudo dpkg-reconfigure -plow dash
I seems to work but again when I reexecute my framework bin I still have the same message...
Someone know how to solve this?
Thank you

no one?

your post is kind of confusing... did you actually try what the installer suggested?

sudo ln -sf bash /bin/sh

you can always revert it after with

sudo ln -sf dash /bin/sh
