Thank you for your suggestions; most of them reflect things I had googled up earlier but did not point to the difficulty. The machine is down currently due to PS problems, so I don't have access to the system or files, and what I write is from memory and some sketchy notes I took --but one of the updates I installed in late April somehow removed the file '50-udev-default.rules' from /lib/udev/rules.d/.
I found this by comparison with another Karmic installation, and in fact fixed it by copying that file to my installation. Problem disappeared. If anyone is in need, I can look through the updates record of that time and (if the packages haven't been replaced since) see if I can find which one did it. If no one is interested, then, consider this bug closed. -- /dev/null: permission denied https://bugs.launchpad.net/bugs/591114 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
