Ubuntu Installation :: Public Key Is Not Available When Checking For Upgrades On Upgrade Manager

When I click "check" in Update Manager it tries to download 541 files, skiping each one and the giving me this message: Quote: W: GPG error: http://linux.dropbox.com karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY FC918B335044912E W: An error occurred during the signature verification.

I'm running 10.04 and for several days now I get two packages that are grayed out and do not upgrade in upgrade-manager.
If I use the shell and apt-get I get the following message: The following packages have been kept back: firefox-gnome-support update-manager
The system is functioning well, but these 2 packages just linger as I process probably hundreds of lucid upgraded packages.

I know 11.04 is available for download at the moment, but it isn't showing up in Update-Manager. I would just put it on a disk and install it that way, but I'm running 10.04 in Wubi. Update-Manager is currently set to receive all 'normal' releases.

when i got my starling netbook 6 months ago it worked perfectly. due to upgrades since then i now have problems with printing, sound and videos. there are probably solutions to all of these things if i spent hours here on the forum asking questions, and trying different solutions, but it seems like a lot of work.
upgrade manager calls these things "important security upgrades". are they really important to security? would my computer be dangerously vulnerable to attack if i never did an upgrade?

I'm running 9.10 and did not upgrade to 10.4 because I thought I'd just wait tor 10.10. However, if I go to Sys/Admin.>Update Manager>'check'>'install'>'check' I do not get informed of upgrade choices.I am trying not to do an install with this because then I would have to reload and reset everything including 80+ CD's. Please help if you can.I know I have to Ugrade to 10.4 before I can upgrade to 10.10, however my update manger offers neither option after installing updates and rechecking.

I'm trying to update an Ubuntu Server install to 10.04. I believe something went wrong when I upgraded it from 8.10 to 9.10 in the past. Currently /etc/apt/sources.list would indicate the system is running 9.10, but /etc/issue says 8.10, as does lsb_release -a.
apt-get update and apt-get upgrade show everything is up to date. When I do a do-release-upgrade it tells me that there are no upgrades available.

I'm not sure if this is the right place to post this, but...well, I just installed Fedora after using Ubuntu for a while, and everything has been going good, except for installing upgrades. When I open the Update Manager, it says there is 399 updates. When I click install, after about ten seconds this pops up:Code:An internal system error has occuredA problem we were not expected has occured. Please report this bug in your distribution bugtracker wth the error description.
More details:
Error Type: <class 'yum.Errors.RepoError'>
Error Value: Error getting repository data for installed, repository not found

I did normal net upgrade after the official release of 10.10 yesterday evening. On reboot I get a frozen system with a blank screen. Checking via safemode, I find it is stuck when 'checking battery state' but this is a desktop machine! Apt update, uninstalling ubuntu-desktop, reinstalling ubuntu-desktop, etc.

I am trying to upgrade from 9.10 to 10.04 beta. I tried ALT-F2 & ``update - manager -d'' but when Upate Manager opened, it did not give me the option of upgrading to 10.04 beta.

I'm running Ubuntu 10.10 and 2.6.35-27-generic. When I run the Upgrade Manager, the 'Distribution Upgrade' window pops up and in bold letters reads 'Running partial upgrade'.
The next line reads '>Preparing to upgrade' and sits there. Mean while, the process begins to perform a great deal of constant hard drive activity. The window's horizontal activity bar reads 'Calculating the changes' at the bottom of the 'Distribution Upgrade' window.

Pretty soon, I hope, I'll get my brand new PC and wish to install a Linux disto. on it. openSuse may be it But I read recently that people prefer to do a fresh install of a newer version of openSuse, instead of upgrading it, apparently because of problems that may occur by the upgrade. As I understand, this preference apply to all Linux distributions and not only openSuse. Thus I wonder if there's a Linux distro. that's best in handling upgrades?I don't want to make a fresh new install each and every time that my disro. has a new version. I'm afraid to lose the data in that installation, and backing-up the data would be a headache. Also I plan to install a Windows OS alongside the Linux one via the Dual Boot configuration.

I changed my internet source from wireless to wired cable which came with a new IP address. Subsequently anytime I try checking for updates from the update manager it still refers me to my old IP address for wireless and here is the results I get:

I'm now using Ubuntu 9.04 and I think of upgrading it to version 10.04 (when it shall be "stable").I'd like to know if I am supposed to modify /etc/apt/sources.list with the name of the new version even though I upgrade by "update-manager-core" with the command sudo do-release-upgrade

Update Manager wants me to update to Firefox 3.5.7. I'm currently running 64-bit Firefox 3.5.6. I'd like to update, but Update Manager says nothing about this 3.5.7 being the 64-bit version. If I upgrade from the UM, I don't know if I'll be getting 32-bit or 64-bit FF. How can I tell beforehand which one I'll get?

Just upgraded to 10.04 and when I log into kdm to find nothing on the desktop. It seems the problem is that the window manager doesn't even load. kde-window-manager is installed but still nothing. What did this upgrade do and how can I fix the window manager?

I've searched the forums (250 thread limit) for a fix on this, but all the questions seem unanswered or unrelated. My situation is this: I'm running Ubuntu x64 10.10 'Maverick'. I have a cablemodem connection for my Internet access. I have home network running on DD-WRT with the dreadful Linksys WRT54G series router.
My DD-WRT router is 192.168.1.1, subnet 255.255.255.0.
My Linux box is 192.168.1.61, subnet 255.255.255.0.
I have a VyprVPN connection set up successfully on Linux. Mostly everything works great, speed's fine, latency is what I expect it to be. Except... I also run an SSH server to remotely admin the box at port 22, an Apache server running over SSL at port 7001, and a Transmission web client at port 7002 (only secured by basic HTTP realms auth). All of these things worked before I got the VPN working, I'm of course using NAT at the DD-WRT router.
The endresult I am looking for, is to have the security and protection of the VPN (even if it's only perceived) for everything I do on this machine -- EXCEPT on Apache, the Transmission web panel, and the SSH server, which I want to access from the outside world. I have no firewalls running or configured, not even iptables, not even the SPI firewall on DD-WRT. All connections to the aforementioned services from the outside world timeout coming in to the Linux box. They all work from inside my home network (182.168.1.0/24). In case it's needed, he's my routing:

This is my fourth on-line upgrade from Gutsy (started with Dapper ...) all the previous one went without a hitch !
So I was pretty confident this afternoon upgrading my Lenovo laptop from 9.04 to 9.10.
At one point during the install, I got error messages and was offer to do a "Partial Install". I accepted, different things happened, rebooted. Update manager came on with again the partial update pop-up. Accepted it again, it downloaded more files, rebooted, partial upgrade window again but it failed immediately.
The network connection was gone, clicking on the network icon I got a message that the network manager is not running.
I cannot check or uncheck the "network unabled" choice.
However, 9.10 is running, slow and weird, but no network connection so I cannot try to finish the "partial upgrade"
Every time I reboot the Update manager pops up.
Trying to boot any previous version in "grub" fails right away saying it is unable to mount the drives ...
Is there a way to start the Network Manager from a terminal ?

Basically, the update manager pops up and... nothing happens. It checks for updates but doesn't indicate upgrade availability.Running other commands like apt-get distribution-upgrade also doesn't do anything.
I think the problem is the fact that I've installed a bunch of software from rep's and ppa's via ubuntu-tweak that are more recent than the ones in Ubuntu's rep, but I can't been sure.Also, I've deactivated all third party rep's and ppa's, but I still have a bunch of software installed via those sources.

I'm trying to do an online upgrade from 8.04 to 10.04 using the update manager. Since update manager did not indicate that there was and upgrade, I used the update-manager --devel-release command to initiate the process. The upgrade stops during while looking for channels with the following error message:
A problem occurred during the update. This is usually some sort of network problem, please check your network connection and retry.
W:Failed to fetch
http://archive.ubuntu.com/ubuntu/dis...kports/Release Unable
to find expected entry main/debian-installer/binary-i386/Packages in
Meta-index file (malformed Release file?)
E:Some index files failed to download, they have been ignored, or old ones used instead. I don't believe this to be a network problem because it fails in the same place every time. I don't see the entry for debian-installer in the Release file which I believe is why the error is occuring, however, I'm not sure what to do about it. It seems like something is pointed to the wrong place. I've maintained this system with update-manager for several years and never had a problem.

I was so impressed by the screen-shots of 10.04 LTS that i wanted upgrade via the update manager( am using karmic 9.10).Everything went well with downloading the new packages till the point of installation of downloaded packages. Halfway through the installation power went off and when i restarted the system it was stuck at some point with the message
Code: mount: nothing to mount in /dev or something like that. Then i restarted the system in recovery mode and ran "dpkg" to fix broken packages hoping it would fix the issue.It did to some extent that i was type the problem here through the affected system.
The problem is i couldn't send the crash report the first time around and i can't get hold of it now.My system is somewhere between karmic and lucid ("About Ubuntu" shows as karmic and System Monitor shows it as lucid").So i how do i get a clean installation of lucid?

I'm noticing that maybe twice a month the Update Manager is asking me to upgrade my kernel. Currently it's asking me to move to 2.6.32.24.25. Is this the smart thing to do? Are these primarily securtiy updates to the kernel?

I started the upgrade to 10.10 and now the upgrade process is trying to get some input in the orange window. Problem is I can't bring that window to the front because metacity crashed. When I try to start metacity from a console it dumps core. How do I continue the upgrade?

I just upgraded from 10.04 to 10.10 and now virt-manager won't start. If I try from the menu, nothing happens. If I try and start it from the command line (as root) it give the error:
GLib-GIO:ERROR:/build/buildd/glib2.0-2.26.0/gio/gdbusconnection.c:2270:initable_init: assertion failed: (connection->initialization_error == NULL)Aborted
I've tried searching and can't seem to find anything related, but was hoping this might make some sense to someone.

I'm running Ubuntu 10.04 desktop edition on one of my machines and its connected to internet via network proxy with username/password authentication enabled.
I've provided proxy details in Synaptic Package Manager and also in System -> Preferences -> Network Proxy. I can see any new updated libraries when I check Update Manager, but somehow I do not see the notice of availability of Ubuntu 10.10 and hence not able to upgrade.
On my home laptop (Dell Inspiron 700m) which connects to internet directly and over there I was able to upgrade to 10.10
So I think there is some problem with respect to update manager where it cant see the new release available behind proxy.

Ubuntu Studio (no idea what version, no idea how to find out) Update Manager has been saying 10.04 is ready for quite some time, but I cannot install the upgrade. The first time, more than a month ago, it had problems with Java and aborted. This time it couldn't find a repository in NZ so it threw up its (virtual) hands and gave up. Should I even try to upgrade? I keep installing maintenance and security updates (except Adobe Flash Player which Adobe cannot identify). It does most of what I want it to do. Does 10.04 (or 10.10) really matter? Assuming I try for US 10.04 LTS again, how do I get it past its problems?

1. Update-manager panel icon changes into do-not-enter traffic sign.
2. If you want to re-install Update-manager using Synaptic, then Synaptic opens for a while and then closes by itself.

Upgrade Manager wants to remove 'gnome' & 'gnome-desktop-environment,' and doesn't want to replace it with anything else. It appears that this will completely hose my Gnome UI and 'force' me to use Unity.
Is this what's going to happen?
This could hose my whole OS... What can I do?
