[Libguestfs] rpm scriptlet failed

Hello, While trying to install a rpm package in a Linux image under guestifish, the following error message is returned: sh "rpm -ivh --nodeps sympl.rpm" error: install: %pre scriptlet failed (2), skipping sympl If I boot the same image in QEMU and run the same command, no error message is returned and the package is correctly installed. The script contents is only a single "exit 0". I don't what could be the cause of this error. Please I would like to know whether any of you have face such a problem before. Thanks in advance. Regards, Alexandre
