[maemo-developers] [maemo-developers] dpkg processing error

[From: Andrey Khurri]

Hi all,

I am trying to install 'ncurses-bin' package from repositories but got 
an error as described below:

Nokia770-26:~# apt-get install ncurses-bin
Reading package lists... Done

Errors were encountered while processing:
 /var/cache/apt/archives/ncurses-bin_5.5-1_armel.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

I checked what is /usr/bin/clear and it was a symbolic link to 
/usr/bin/busybox. Then I tried to remove this link so there is no 
'/usr/bin/clear' anymore but it does not help. I get the same error as 
before.

I would be grateful for your ideas how to fix this.

Andrey
