Ubuntu :: Updates Screws Up Grub?
Jun 5, 2010
Both my netbook and this machine needs an update (according to the update manager) Well 2 days ago, I let it update the netbook. Bad mistake. Long story short; it installed a new kernel, and monkeyed with GRUB (v1.5) and it wouldn't boot. It's that new grub thing, with the long cryptic numbers/letters string, instead of the more normal hd0, hd1 thing. I had no clue on how to restore it.
How can I back up GRUB next time, let it update, then restore grub back the way it's suppose to work? I tried backing up the menu.lst file, but that didn't work. I backed up, and restored it, and the netbook still wouldn't boot. Got the very same error message. I had to do a partimage to bring back the old image of it. Also Grub-install will not work at all, from systemrescueCD.
Is there some sort of up-to-date tutorial on Grub? I've had more problems with Grub than anything dealing with linux. Especially since anything happens to it, your virtually screwed.

Since network file systems seem either broken or slow, I'm trying to get VNC working.Basically it does work. But the clients I've found so far are very clunky about moving around the screen of the server system, there doesn't seem to be a clean way of exiting the client, and now the keyboard on the system which I ran the client on is completely screwed up.I need something sane here.First, how do I get my keyboard working correctly again?Second, is there a VNC client that's actually any good?

Every time 10.04 updates I find that two of my programs - boinc and CUPS - get de-configured and must be either reconfigured, or re-installed to make them work. While the fix itself is easy, it is an inconvenience to have to do this after every weekly update. Why this is happening, what I can do to prevent it from occurring in the future (aside from not updating).

Thats it in a nutshell. and I don't mean the boot splash graphics, I mean desktop graphics! As in upon boot ubuntu goes in "low-graphics" mode. I have had this issue all the time with Lucid and never really found a good fix. With Karmic this was never an issue.As a final fix I tried to reinstall lucid and updated the live CD doing that too. First it worked fine, but after kernel update I downloaded yesterday (with update manager) I have had this "low graphics" issue again.
With Graphics card, I have nVidia GeForce 220 GT. The drivers are up to date, active, and in use. (according to the "hardware drivers" tool.

Can't seem to figure out how to make usable recordings with my webcam in cheese. when making very short video's like a few seconds...the longest so far was 11 seconds, it will behave just fine and it outputs a playable file with thumbnail and all. But when I try anything longer something seems to go wrong. I can tell first because cheese refuses to display a thumbnail for the resulting video. But also I cannot play it n any player I have (Yes I have pretty much all the codecs) Also when saved as a seperate file Gnome will choke when I try to get it to display properties for it.
I haven't found any errors like this when googling for cheese. Oh my OS is 10.04 and I have the 2.30-something Cheese that's packed for this version (can't get any of the newer cheeses to compile on it so far)

I'm having a problem with Wubi on my netbook, and while I could fix it easily (though probably only temporarily) by reinstalling, I've been using it since January and many of the files are files I cannot afford to lose. I'm dual booting with Windows XP, but when I choose Ubuntu 9.10 from the menu at startup, it takes me straight to Grub with the following message:
Quote:
GNU GRUB version 1.97~beta4 [minimal BASH - like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device/file completions.] sh:grub>
I've had this problem once before, but I was able to fix it with the wubildr patch. Both instances of this problem have occurred after updates, though it hasn't happened after every update, just the two so far.I've also tried several of the command-line suggestions that have fixed this problem for other users, but I've been getting "unknown filesystem" when I attempt them. If anyone has any idea how to fix this without losing the files I have on my current install,

I've been a Windows users since waaaay back when (ahh...Windows for Workgroups 3.1). I've tried Linux in the past (Mandrake many years ago), but didn't feel it was quite ready to be a Windows substitute for me.A couple of weeks ago, I downloaded the latest version of Ubuntu (10.04) and installed it in a dual boot setup with Windows XPSP3. All seemed to be running well, until it came time to install updates in the Update Manager. First an update for GRUB, which promptly killed GRUB and left me with "Minimal BASH-like line editing is supported" message and a GRUB prompt. After booting up the Windows XP install CD, I was able to rewrite the MBR and get back into Windows.
I deleted the Ubuntu installation and reinstalled it, making sure I didn't allow it to update GRUB after finishing up. The other updates listed installed fine and I was able to dual boot with ease.Another round of updates were listed yesterday when I booted up in Ubuntu, I made sure not to include the GRUB update, downloaded and installed them, rebooted and was faced with "Minimal BASH-like line editing is supported" again. Argh. Once again I had to pull out the Windows CD and run FIXMBR to resolve the boot problem.I'll admit to being tempted to just go back to Windows completely (while not perfect, atleast I can get it to boot after updates 99.9% of the time) and forget the idea of running Linux if I'm going to be faced with having to reinstall the OS everytime because something killed the boot loader.

I'm dual booting Win7 & Ubuntu 10.04 on a Gateway NV78 series laptop, and while on the Windows side, the Gateway Update Manager asks to update my BIOS. If I allow it to do so, will it mess up Grub? For bonus points: how could I fix Grub if the BIOS updates does damage it?

since some update to the latest Flash, I've been getting a weird issue. If I'm watching a flash video in fullscreen (via firefox) and hit "esc" to leave full screen, about 20-40% of the time it will screw up the monitor's display of everything. The entire screen gets weird white and colored pixels randomply all over the screen (see the attached picture). Restarting is the only thing that fixes this. I tried logging out and back in but the issue remains. I have two questions:
1. How do I fix this without a restart?
2. What could be causing this?

I'm used to kernel updates screwing up both my graphics drivers and my instaltion of parallels. These things break each and every time the kernel is updated. Normally, reinstalling makes the problem go away and I move on. Yesterday, Parallels got screwed and I fixed it by reinstalling but the graphic driver is yet to work.
For reference I am using OpenSUSE 11.2 64-Bit Gnome-Edition with an ATI Radeon 4650, since it probably makes a difference. For some reason the driver from the repo (ATI's repo) would not install and I got errors saying that it has a wrong signature and (ignoring that) I got another error saying it was corrupted. So I could not install as usual.
Instead I went at ATI's site and downloaded the latest driver. It installed but I lost the mouse cursor so I reinstalled the previous version which also installed but it not working properly, although I do have a mouse cursor.
glxinfo gives the following error:
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 136 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)
Serial number of failed request: 24
Current serial number in output stream: 24
fglrxinfo outputs the exact same thing. OpenGL is not working in any way. Even the gears demo and desktop effects (which I tried to reactivate just to test, since I hate those things) simply do not work.

After I updated my system, grub shows about 2 extra options on the boot menu. They seem to be different kernel versions. How do I clean up the menu and uninstall the older kernel versions?

I'm remote from my system and so have to wait 2-3 days before I can get access directly, but I've noticed that when the kernel updates automatically (or forced by me), the next reboot stops at the grub page awaiting confirmation of the kernel I want to boot. grub.conf doesnt seem significantly different from that of fedora (my previos distro for this machine) and even has the default lines and times spec'd, so I can't see what's holding it up. Any ideas how I can prevent this so I can have my system auto-updating the kernel AND safe to reboot remotely?

Just installed Ubuntu a month ago (installed within windows), and for the 2nd time it has gotten stuck in grub upon restart after doing an automatic update. Last time, I reinstalled from the CD, but I can't do that every time. Learning how to start up from grub would probably be worth learning so I don't have to use the CD. But fixing the problem is most important. It makes me wonder if it was a mistake to install Ubuntu from within Windows (does this mean I have "wubu"?). I did find a webpage on booting Ubuntu from grub, but I could not get the kernel to load, regardless of if I used the instructions for wubu or not.

I'm currently running Karmic 9.10 in dual boot with Windows 2000. My computer has automatically updated and installed kernels 2.6.31-17, -19 and -20 (They show up in Synaptic as installed).
However, the newest kernel choice in my GRUB menu is 2.6.31-16-generic (followed by -15 and -14). These all start without any errors.
Question: Why haven't the newer updates shown up in GRUB for booting purposes?
Could it be a question that I didn't answer correctly some time back about accepting or not accepting an update or change in GRUB?
How can this be changed? The new kernels do not show up in Start-Up Manager either.

How can I uninstall grub? I have have dual boot between Gentoo and Ubuntu and I want to use the grub, that is on Gentoo partition, as its my main system. I would not care about it as it takes almost no space, but Ubuntu automatically restores its own bootscreen after updates. This is annoying... How to get rid of it?

After applying the latest round of updates last night, I turned on my laptop this AM (ATI X1300 Mobility graphics running the default drivers), selected the latest kernel in GRUB, and waited to log in....only problem is that instead of seeing a normal loading screen (Blue with Fedora icon filling in), I instead get a black screen mostly covered in multicolored rectangles. I don't believe there was a graphics driver update, so I'm rather confused as to what went wrong/how to procede. I can still boot using a previous kernel.

Today it happened again: After an apparently trivial update Grub (Grub2) enters rescue mode the next time booting, not displaying any useful help whatsoever at that point. (Remember that at boot time no manual or help pages are available.) I don't know what went wrong, but ... The harddisk or partition in question is now no longer a bootable partition.
I don't want to use much time trying to sort out things, so unless someone may direct me to at better procedure, I am going to save whatever can be saved from the hd and then reinstall debian (in this case: Sqeeze) from scratch. Nothing else has in my experience ever worked before.

I'm kinda new to Linux. My problem is that a new Fedora O/S entry is added onto grub everytime I receive an update on Fedora (I think). Eg:
Fedora 15 15.40.0-4 ...
Fedora 15 15.40.0-3 ...
Fedora 15 15.38.0-0 ...
Windows 7
How do I stop this? Ideally I'll only have two entries, Fedora 15 and Windows 7 where Windows is set as the default primary o/s to boot up. The current method I use is to fiddle around with that grub file and set default to entry 3, which used to be Windows 7 but is now a Fedora (which means Fedora is now set to default boot up).

I dual-boot my machine and I want it to default to boot into windows so that whenever I restart the machine remotely from my home it will be able to get back into Windows (instead of Ubuntu).
The problem is that every time Ubuntu upgrades the kernel, I have to reset the default boot item of grub back to windows. This is because the grub menu loader uses positions i.e. 6 for default OS to boot. And when Ubuntu installs a new kernel it changes that order.
I am looking for a way to configure grub to remember its default boot item under kernel updates.

For some reason Update Manager is not installing updates as of yesterday.I have it set to check daily and notify if updates are available. It has been working without issues for well over a year now.
Update Manager tells me updates are available and presents the list of security, recommended, and other updates. All are selected to update, but when I select Install Updates in Update Manager it returns with a Reading Package Information window overlaid on the main Update Manager window - building dependency tree then reading state information and dumps me back to the main Update Manager window without performing any update actions.

I just learned that warsow 0.6 is out, and went to see if it was available in the ubuntu software center yet, as opposed to going and downloading and installing it manually from the warsow website. The ubuntu repo's still have version 0.5, and at the bottom of the page it says:
"Updates: Canonical does not provide updates for Warsow. Some updates may be provided by the Ubuntu community."
So if I wanted to 'update' this item in the repo's for the better of the community what would that entail?

There are some updates in the Update Manager list which I do not install. Among them, some drivers for HP Printers (I don't know why this cropped up; I don't even use printers on my laptop), and gcj updates (I use gcc/g++ but not gcj). I unchecked them the first time I saw them on my UM list. However, for every subsequent batch of new updates, UM retains these updates and I need to uncheck them every time. How can I remove them totally from my UM list?

So, it is my understanding that Ubuntu's automatic updates do not install ANY updates that are not "important security updates." For example, it did not upgrade me to Firefox 4 automatically; I had to do it myself (Don't all new browser versions usually contain new security features/patches? Oh well...That is a separate question entirely).
ANYWAY, is there some way to get the latest stable versions of all of my open-source software automatically (or at least all at once, on command), instead of just security updates? It seems silly to have to install new versions for every program manually.
Also, related/side question: Now that I have installed Firefox 4 myself (via apt-get by adding the mozilla-stable PPA), will I stop getting security updates for Firefox through the standard Ubuntu update manager?
Actually, a really thorough explanation of the whole automatic update system (or a link to one) would be great too.
