Hi,
One of the reasons that ltib fails to install on Ubuntu is the rpm package. Ubuntu has a patched version of rpm with a different behavior than what you get in Fedora. Mainly it will refuse to install any package unless you give it "--force-debian" flag. Even then, you might get into other problems.
On a clean installation, the error message is:
mkdir: cannot create directory `/opt/freescale': Permission denied
However, before that is another message that hints to the problem:
rpm: please use alien to install rpm packages on Debian, if you are really sure use --force-debian switch. See README.Debian for more details.
The solution is to remove Ubuntu's rpm package together with rpm-dev and install it from source. Follow instructions from the rpm INSTALL file and then run:
$ ./ltib
as instructed in the ltib documentation
For example:
$ ./configure CPPFLAGS="-I/usr/include/nspr -I/usr/include/nss" --with-external-db --without-lua
$ make
$ make install
$ ldconfig #to update the include paths
rpm will be installed in /usr/local/bin so you must update also the sudoers file.
Best regards
