Thank you for these clarifications. About being filled automagically, as far I could tell, it should be assisted bug reporting.
Well, not sure it is a physical problem with the disk. After all, there was indeed an error with hdc: PLEXTOR CD-R PREMIUM just before it began reporting errors on ata3. And an other suspicious thing before errors on ata3: Nov 2 20:03:51 ubuntu ubiquity: swapon: /dev/sda5: Device or resource busy Anyway, I am not closing this bug, but rather marking it as Confirmed, to attract the attention of a developer that will decide what to do next, and that could be able to give a more expert advice than me. Thanks again for your bug report and the followup! ** Changed in: ubiquity (Ubuntu) Status: Incomplete => Confirmed -- Installer crashed with IOError: [Errno 30] Read-only file system https://bugs.launchpad.net/bugs/69955 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
