This is the reason of GRUB refusing to update itself ... I installed with aqemu, then some days later I tried to update GRUB running the VM via the CLI. So much for thinking aqemu is a just a simple GUI for running qemu VMs. It evidently does its own tha'ng. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Ubiquity is the installer prom, which is run by the desktop icon with no arguments. Running it from a terminal with -b means no bootloader is installed. -- Neil Bothwick "Time is the best teacher., unfortunately it kills all the students" pgpQgee4FIs9z.pgp Description: OpenPGP digital signature

For future reference, start the Mint installer with "ubiquity -b", then t doesn't install a boot loader at all and you can add it to your Gentoo bootloader after rebooting. -- Neil Bothwick WinErr 018: Unrecoverable error - System has been destroyed.

Many an installation were hosed lately because of a GRUB problem in Mint and potentially *buntu.

I checked the permissions for iscan-data & they seem ok. No, I've never tried to use Selinux. However, I've just escaped fr another beast, ie Linux Mint 19 : DON'T try to install it alongside Gentoo !! This beast leads you along to a point where you've told it where to install -- a partition on my HDD (sdb5) -- , you click 'proceed' & it chugs along nicely for some time, then it says it's trying to install a bootloader without asking whether you want it to or where to do it. Next, it says it's failed to install Grub -- which I've never used -- , offers several ugly-looking options & freezes. All you can do is a hard power-off & when you restart, instead of the regular Lilo box of options, there's only a Grub prompt. Disaster looks you in the face ! SystemRescue to the rescue : Gentoo /boot is unaltered, so copy lilo.conf into the SR /etc dir, edit it to use SR paths, mount the Gentoo /boot , run 'lilo' & the MBR is restored to what it sb. Reboot & the familiar Lilo screen appears ! I wanted to see whether the latest Mint found my scanner, which would suggest that the problem doesn't involve the kernel, at least. I'm not trying again ! On inspection, Mint 19 does seem to have installed itself on /dev/sdb5 , so I can copy the vital files from its /boot to my own Gentoo /boot , edit lilo.conf accordingly & see if it will start : not today ! Next up -- too late for today -- is to see if I can get Nvidia working with an earlier kernel : at present it isn't. Then I can find out if Xsane can find my scanner with another kernel. Can anyone take a look at my Strace output ( 3 files), which is at http://chass.utoronto.ca/~purslow/test ? That would be a real help. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca
