Still no joy. Carefully followed the instructions on that web page, and got nowhere -- at least, the same stuff happened as last time -- inability to reread the partition table, and later, inability do deal with logical volumes. Yes, I included the installer modulers for lvm and raid, and for good measure, also the one for mouse-usage, and evms (just in case) But I continued the install anyway. I was installing the system to /dev/hda1, which was not part of a RAID or a logical volume. It went nicely. I had it install grub, uneventfully. When I had it install lilo to boot from /dev/fd0, however, it complainmed that that wasn't a hard disk. Really, I think I should have been able to boot from a floppy. So I had it install lilo bootine from /dev/hda, which created an appropriate configuration file (which I would be able to edit later), and then had it intall grub to /dev/.hda, which worked. I've discovered in the past it's good to have as many different ways to boot as possible. The reboot into the newly installed system went smoothly. But then came the time for package-selection. Even choosing just a minimal system, it complained about: * E: Unable to correct problems, you have held back broken packages. * E: Unable to correct dependencies, some packages cannot be installed * E: Unable to resolve some dependencies * * Some packages had unmet dependencies. This may mean that you have * requested an impossible situation or if you are using the unstable * distribution tht some requested packages have not yet been created * or moved out of Incoming. * The following packages have unmet dependencies * python-minimal: Depends: python 2.3 (>2.3.5-1) which is a virtual package * report-bug: Depends: pythin 2.3 which is a cirtual package * locales: Conflicts: base-config but 2.76 is to be installed * python: Depends: puthon2.3 (>=2.3.5-1) which is a virtual package * tasksel: aptitude failed * Press Enter to continue I had specified manual package selection, but never got the opportunity to manually select any packages. I got past this stage by removing the asterisk from beside "minimal system", thereby asking it to install *nothing*, not even a minimal system. Once I actually got to log in as root, I edited /etc/lilo.conf and got the system to boot proberly from a floppy. Now I could boot from floppy as well as from /dev/hda. I then ran aptitude, intending to try to fix things up. Now, however, the complaints were completely different. I did a U, to upgrade to current versions of everything, and then 'g', and in the list of proposed actions, was told that aptitude wanted to delete base-config libapt-pkg-perl localization-config Investigating, I was told base-config is empty, no longer used, can be deleted without harm libapt-pkg-perl was unavailable localization-config depended on lipapt-pkg-perl, so broken. Clearly a few things need to improved before etch goes stable.... In a few days, I will try again, this time setting up a smaller RAID partition for immediate use, leaving the bulk of the hard disk free for later installation of RAID and LVM when I figure out what's been going so wrong ... or else that I learn how to set up a RAID drive inder LVM in such a way that everything is recognised upon reboot. I suspect I had trouble with RAID-nonrecognition in the past when I was still trying to install sarge... That time I set up the RAID1 and LVM by hand. I suspect that on reboot the RAID was not recognised, but the (now duplicate) LVM were -- at least the first one was, and the second was considered invalid because of name duplications. When I tried to reconfigure LVM, only one copy was, presumably, changed, setting the stage for trouble ever since. Perhaps I should do a destructive bad-block check on /dev/hda3 and /dev/hdc3 just to clear everything out properly. WOuld that do the trick, or is there stll information elsewhere I need to clean out to be able to start over? By the the way, what is the RAID partition I built on /dev/hda3 and /dev/hdc3 likely to be called? -- hendrik -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
