(xubuntu) Help solving package problem please

gregg3; Well, we could hope !

Here:

You can also chose the default by the name instead of index, e.g.:

GRUB_DEFAULT='Ubuntu'
if there was a menuentry 'Ubuntu' line on /boot/grub/grub.cfg. This may be a better method, as it does not depend on the order of the entries, which could change.

As to the release upgrade:
You can set the update-manager to "any" at any time . The prep work for the release upgrade is best done by you . 3rd party (PPA) is not ubuntu . And the system may or may not be able to cope well . That does include a proprietary driver .. not ubuntu ... some cleaver programming to make it work in a particular environment. When the environment changes the software breaks .
---------------

Let's look at what grub has set for booting currently:

ls -al /vmlinuz*
ls -al /initrd.img*
ls -al /boot

Now there is another thought ... we see what we shall see.

we have the will

look'n to find that way

gregg3; Well, we could hope !

Thanks Bashing-om. (Yes, hope is a good thing!) Okay, I'm still hoping to make that next upgrade work. So following this:

You can also chose the default by the name instead of index, e.g.:

  GRUB_DEFAULT='Ubuntu'
  if there was a menuentry 'Ubuntu' line on /boot/grub/grub.cfg. This may be a better method, as it does not depend on the order of the entries, which could change.

I went to my /boot/grub/grub.cfg file and found this:

export linux_gfx_mode
menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-da6f1e1f-a2ff-4eed-8168-44dd46a8c2a8' {
    recordfail
    load_video
    gfxmode $linux_gfx_mode
    insmod gzio
    if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
    insmod part_msdos
    insmod ext2
    set root='hd0,msdos1'
    if [ x$feature_platform_search_hint = xy ]; then
      search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1  da6f1e1f-a2ff-4eed-8168-44dd46a8c2a8
    else
      search --no-floppy --fs-uuid --set=root da6f1e1f-a2ff-4eed-8168-44dd46a8c2a8
    fi
    linux    /boot/vmlinuz-4.4.0-22-generic root=UUID=da6f1e1f-a2ff-4eed-8168-44dd46a8c2a8 ro  quiet splash $vt_handoff
    initrd    /boot/initrd.img-4.4.0-22-generic

So I have the

menuentry 'Ubuntu'

line.

So all I have to do is use nano to go into the /etc/default/grub file and change

GRUB_DEFAULT=4

to

GRUB_DEFAULT='Ubuntu'

, right? And it's

GRUB_DEFAULT='Ubuntu'

, not

GRUB_DEFAULT=Ubuntu

, right?

And I'm wondering, Can I do that now already? Or should I do it right before the distro upgrade in October?

As to the release upgrade:
You can set the update-manager to "any" at any time .

I just did.

The prep work for the release upgrade is best done by you . 3rd party (PPA) is not ubuntu . And the system may or may not be able to cope well . That does include a proprietary driver .. not ubuntu ... some cleaver programming to make it work in a particular environment. When the environment changes the software breaks .

This does not sound ecouraging, especially as how I don't know how to do the prep work. I think I'll just have to throw myself at the mercy of the Sky Penguin and hope the distro upgrade works somehow. (This seems to be such a mess--maybe it is a bug and they'll straighten it all out before I upgrade.)

[/QUOTE]

So it looks like 4.4.0-22-generic is the one that's booting from the power switch, right?

Thanks.

[Bashing-om]

gregg3; Welp;

Grub2 edit:
see: https://help.ubuntu.com/community/Gr...iguring_GRUB_2

something like:

GRUB_DEFAULT="xxxx" An exact menu entry, including the quotation symbols, may also be used. In this case, location in the menu will not matter.

Example: GRUB_DEFAULT="Ubuntu, Linux 2.6.31-9-generic"

This does not sound encouraging, especially as how I don't know how to do the prep work.

nothing to it: disable PPAs in Software Sources and in Additional Drivers make sure the open source graphics's driver is enabled. Easy as that.


Booting kernel:

uname -r

tells that tale. I do not see a thing wrong with how the system installed the kernels .

So we are back to reading the logs if we are to continue to pursue the booting issue. And, I do not know where that will lead.

But ->

inquiring minds want to know

In the /etc/default/grub file (via Nano) I would change:

GRUB_DEFAULT=4

to what?

To

GRUB_DEFAULT='Ubuntu, with Linux 4.4.0-22-generic'

?

Something else?


Okay, you wrote:

disable PPAs in Software Sources and in Additional Drivers make sure the open source graphics's driver is enabled. Easy as that.

Please check the three (hopefully pertinent) screenshots and tell me how to accomplish the above two actions.

And lastly:

Booting kernel:

uname -r

tells that tale. I do not see a thing wrong with how the system installed the kernels .

gregg@LG:~/Desktop$ uname -r
4.4.0-22-generic
gregg@LG:~/Desktop$

And so since the computer picked up on the shift from 4.4.0-21-generic to 4.4.0-22-generic (and it boots from the power button) just leave

GRUB_DEFAULT=4

as is, right?


Bashing-om, If I can feel confident I can go through the 16.10 distro upgrade satisfactorily I'll be very happy. The computer is working great. This last time it came on after 17 minutes. I know that's ridiculously slow, but maybe it's a bug and the coder guys will fix it on their end.

P.S. That'll do it for me tonight. Have a great night! And thanks!

[Bashing-om]

gregg3; Uh huh ...

If you count the menu entries .. 1st entry as '0' .. then you see that '4' is now " Ubuntu, with Linux 4.4.0-21-generic' ".
What kernel do you want as the default booting kernel ? If it is " Linux 4.4.0-22-generic' then reset in /etc/default/grub back to '0' .
Else, sure, lets try " Ubuntu, with Linux 4.2.0-35-generic " .
I am a bit confused; I do expect the the kernel booted from the power button to be what you have set in /etc/default/grub (4) to be that booting kernel !


Software and Updates -> other software tab: are your PPAs. As you have it set now .. will not get updates for any of the PPAs except google-chrome. Need to check and see if these PPA's are supported in 16.04 and perhaps re-enable them .
Software and updates -> Additional drivers tab : You have no -proprietary- drivers in use or available .

As is now .. if you were to do a release upgrade now .. I would expect no problems.

[Bashing-om]

gregg3; Hey !

Here is another thought to see what is going on with the delay on booting.
Watch the boot messages as you are booting .
To unhide the boot messages:
In the /etc/default/grub file the line: " GRUB_CMDLINE_LINUX_DEFAULT="splash quiet" remove the terms quiet splash, such that it becomes: GRUB_CMDLINE_LINUX_DEFAULT=" "

remember to run

sudo update-grub

after you have saved the file .. to propagate the change.

we can do that too

Thanks Bashing-om. But before I do that (since I have to use the computer now), I figured I'd mention something else about the booting process. When I boot, I DON'T get the Xubuntu screen at all. It's just the black screen with the RAM info type stuff and then 'Loading Operating System' and then the screen goes black and I get the "No input signal" window. Then the monitor shuts off. And then (say after 17 minutes or so) the computer does not come on unless I scroll the mouse.

I don't know what that might mean and I got used to the computer booting that way so didn't think of mentioning it until now.

Thanks.

Hi Bashing-om. Yes, I counted the entries (and is it the case that the #0 and #1 entry are the same {in this case: 4.4.0-22-generic}?) and I can see that #4 is 4.4.0-21-generic, but the fact of that matter is the computer boots to 4.4.0-22-generic. Here's the terminal data:

So that makes no sense.

What kernel do you want as the default booting kernel ? If it is " Linux 4.4.0-22-generic' then reset in /etc/default/grub back to '0' .

Yes, I want 4.4.0-22-generic. I can try the reset to '0' but I already tried that (granted, with a different kernel) in post #92 point #5 and the results are in post #94 point #5. (When I reset to '0' it just led to the "No input signal" black screen.) So the computer just seems to be booting the #4 spot as the #0 spot.

Else, sure, lets try " Ubuntu, with Linux 4.2.0-35-generic " .

Not sure why you say this. You're saying: GRUB_DEFAULT= "Ubuntu, with Linux 4.2.0-35-generic" , right? Why would I do that when I want to boot 4.4.0-22-generic?

I am a bit confused; I do expect the the kernel booted from the power button to be what you have set in /etc/default/grub (4) to be that booting kernel !

As you can see (from the terminal data) that's not the case.

Software and Updates -> other software tab: are your PPAs. As you have it set now .. will not get updates for any of the PPAs except google-chrome. Need to check and see if these PPA's are supported in 16.04 and perhaps re-enable them .

Okay, I looked those PPA's over. They were hard to understand. As you said only Chrome was enabled. The others appear to have been disabled on different distro upgrades. I do use things of course from Canonical, but in that grouping I also mkusb, steam, bit (Back In Time) and Mega. I do not know (nor could I find out via Googling) how to see if the PPA's are supported in 16.04. My best guess would be just to check the ones I'm using. Would that be prudent?

And what about things like Firefox? Does that get updated in a different way? (This whole "other software" updates is news to me.)

Software and updates -> Additional drivers tab : You have no -proprietary- drivers in use or available .

Okay, so that's good.

As is now .. if you were to do a release upgrade now .. I would expect no problems.

Good also.

Thanks.
