I started yast in one console and selected Software Management in the right sub window without pressing Return. In a second console I gave the command: ps aux to find the pid of the y2base process after that I gave the command: strace -ff -p 25721 >strace.1 2>strace.2 I pressed Return in the first console and after reappearing of the main ncurses window of yast I entered <Alt>Q, which also ended strace. I found only strace.2 having output. I will send that in a separate private message. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-arm+unsubscr...@opensuse.org To contact the owner, e-mail: opensuse-arm+ow...@opensuse.org
