Ubuntu :: Disable Update To Natty For Public Computer
Apr 29, 2011
I have to manage a publicly accessible computer, and people know the password and are willing to click just anything, that pops up and has a "yes"/"ok"/"i agree" button on it, just to make the message disappear. (yes, I hate their ignorance ...) As long as they can use the net, that is all they care about...
My question is, can I still get updates for Maverick without being prompted for upgrade to Natty? Also I would like to remove the button from Update Manager. Is there a simple way to do that?
So after tinkering for a while, I was able to configure ssh for private/public key authentication and disabled Password-Authentication. In the past I had some issues with people brute force trying passwords/usernames so I want to avoid this, but I need some form of secure FTP that now doesn't work due to the aforementioned setting.
Our local community wants to provide broadband access for people who don't own a computer. I have been given the task of setting this up and I am going to use Ubuntu. Internet access will be via a usb dongle to a T-Mobile 3.5g network. Initially we are intending to limit access to just Internet browsing. Most users will probably be older people, rather than teenage hackers. configuring/securing a default Ubuntu install for this sort of use.
I recently installed Ubuntu 10.10 on my sister's HPtx2000 since she isn't going to use it anymore and it worked better than I expect. The touchscreen works without any additional driver tweaking and installation <3, the wireless works fine, the sound works. I listed those because when i was installing, I was looking around at other people that did this and those were the problems they had (but those was of an old OS).
Well anyways, what I want to ask is about the stuff that doesn't work and the stuff I want to do: The buttons that flip the screen and etc doesn't work. Is there a way to map them and flip the orientation of the screen? And the other buttons too, like the media button. Is there a way to map them to open VLC or something? Does anyone know any tablet programs for Ubuntu? E.g a simple text program that can convert stuff written to neat, typed font? A way to write text into a google search bar using the stylus? And while we're on this, is there a way to map a left click on the touch screen?
In Windows, the left click could be mapped to: a). a side button of the pen, b) the top button of the pen, and c) holding the pen down onto the touchscreen. how to use Samba to access a public folder of a Windows computer? And to access the printer connect to the Windows computer? Some of the tutorials I found were only for folders and printers on the Ubuntu computer.
I just upgraded machine to natty, after which the xmodmap configuration remapping capslock stopped working (as in not doing anything at all). Running xmodmap manually (-e "clear Lock") doesn't have any visible effect either. I haven't tried doing this on another machine (I'm only close to one machine running ubuntu and reinstalling seems rather overkill), but the same config worked before the upgrade, and is working on another machine running arch.
Is anyone else having these issues and, if so, has anybody found a solution? The line of interest is, simply, "clear Lock".
The public key isn't available when I try to use the Update Manager; clicking the "Check" button results in a popup with the following text:
Code: W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6E871C4A881574DE
Chkconfig is a utility to update and query runlevel information for system services. Chkconfig manipulates the numerous symbolic links in /etc/init.d/, to relieve system administrators of some of the drudgery of manually editing the symbolic links.
In Debian, there are several tools with similar functionality, but users coming from other Linux distributions will find the tools in this package more familiar.
Go to Terminal and open it and type the command "chkconfig' press enter. code...
after installing just type "chkconfig" you can see list of service which one is off or on in your system code...
I have added the following line in sources.list, deb [URL] squeeze main non-free
Running apt-get update i get this error message, Reading package lists... Done W: GPG error: http://www.debian-multimedia.org squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 123456789
Do i need to generate this public key 123456789 ? If so, how?
Running apt-key update has not solved the problem.
apt-get install debian-archive-keyring was a recommended solution from some googling.
I have also read this page, [URL] , but how to add a key is under construction.
I turned on my debian systems. Update tells me that I have 26 updates, mostly to samba. I proceed and it gives me an error saying something about public key not available. Suggests to try smart update. I do that, smart update says I have 129 updates available (reasonable I guess b/c I have not updated in close to a year)
I proceed with smart update...now it says I can install 137 updates, I hit Check, tells me it is downloading packages, then, I get an error: W: GPG error: http://code.highrise.ca lenny Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B95C4D3ECC4D3D27
I don't understand why....What is the solution for this?
Is there a way to disable all popup notifications in openSUSE while still having it check for updates periodically. What I would like is for the notification icon to appear when an update is available but to not popup the notification message, or worse, show that dialog stating that some software sources were not available when I'm on the corporate network.
Also, is it possible to disable some updates like the recent KDE one? I right click it and there is an option to disable notification of an update but the menu item is disabled.
I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive
How do I update Empathy on Natty to it's latest version? I've been having trouble to figure it out.. The version that comes on Ubuntu 11.04 doesn't even have an icon that tells me which contacts are on mobile.
i have a healthy and fully operational mobile broadband connection yet i cannot update my Ubuntu 9.10 computer. every time i try to update i receive an error message with the title: "could not download all repository indexes", the information the dialog box contains is as follows
GPG error: http://flomertens.keo.in edgy Release: The following signatures were invalid: NODATA 1 NODATA 2GPG error: http://ntfs-3g.sitesweetsite.info edgy Release: The following signatures were invalid: NODATA 1 NODATA 2Failed to fetch http://flomertens.keo.in/ubuntu/dist...6/Packages.bz2 Sub-process /bin/bzip2 returned an error code (2)
The following errors show up when I run from the file from the term window, but are not written to log.log:
tar: /public/public/clamscans/*.txt: Cannot stat: No such file or directory tar: Error exit delayed from previous errors mv: cannot stat `/public/public/clamscans/*.txt': No such file or directory
I know with windows you can add the 2>&1 to capture error data. Is there such a thing for Linux?
After updating to natty I cannot compile any Gtk+ code, no matter what I do I get linker errors. This is not a problem with the way I'm building it, I'm familiar with the correct usage of pkg-config.
Even this code will fail to link: Code: #include <gtk/gtk.h> int main(int argc, char** argv) { gkt_init(&argc, &argv); gtk_main(); } (Compiled with the standard commands to compile Gtk+ stuff)
I always get the following output: Code: /usr/lib/libgtk-x11-2.0.so: undefined reference to `g_source_get_time' /usr/lib/libgtk-x11-2.0.so: undefined reference to `g_get_monotonic_time' /usr/lib/libgdk_pixbuf-2.0.so: undefined reference to `g_simple_async_result_take_error' /usr/lib/libgdk-x11-2.0.so: undefined reference to `g_slist_free_full'
I accepted the latest Natty update about which I was notified a couple of days ago (I don't remember exactly). I don't remember a new kernel being pushed out, but for the record I'm on 2.6.38-8-generic right now. I'm trying to interact with a USB compact flash reader and I'm getting ridiculously low throughput (less than 1 MB per second). Before this latest upgrade, I don't remember this being a problem.
Better yet, does anybody know what might be wrong and what I might be able to do to fix this?
I have an 10.10 Maverick Ubuntu, and I've tried to update it to Natty version, but when I try it says to I check my connection with Internet and then close the update app, but my connection is fine, I think this could be something related to the host, since when I try to use sudo or play Frets on Fire it says that they "couldn't resolve the host".
Is there a way to disable the "upgrade to natty" pop-up window on Maverick? I currently have no intentions on upgrading, and the pop-up is very annoying when I'm typing, and suddenly There It Is
How can I forward all traffic from a public IP to another public IP. Let's say I have a first debian box named box1 with eth0 = 1.1.1.1 and eth0:1 = 1.1.1.2 and I want to forward all traffic from 1.1.1.2 to "box2" located somewhere else over the internet and having for eth0 2.2.2.2 Both 1.1.1.0/24 and 3.3.3.0/24 are public IP ranges.
Since I have updated last night from maverick to the latest beta of natty narwal, I'm having a lot of trouble getting Nautilus (desktop included) to work.
It seems to crash since the very start as when I turn off the computer, the message of "force exit" appears.
Currently I am trying to update my drivers in 11.04 on a dell inspiron mini. I do not believe it is a pure dell problem, as my regular dell xps running 10.10 has been having to problems updating.
I go into additional drivers and start having it search but it gets stuck and states: Downloading package indexes failed, please check your network status. Most drivers will not be available.
Does this mean the servers are just really busy? Or do I have a problem somewhere on my end?
I was messing around with some stuff I probably shouldn't have when trying to get my Intel graphics card working better (that's another problem completely). Now the update manager has ceased to work. Every time I try to use it this error pops up:
Quote:
Could not initialize the package information
An unresolvable problem occurred while initializing the package information.
Please report this bug against the 'update-manager' package and include the following error message:
'E:Type [url] is not known on line 57 in source list /etc/apt/sources.list'
When I run the update manager in XUbuntu (natty/11:04) it does not show its progress while installing the upgrades.
After clicking on "install updates" and authenticating, there used to be a popup window with a progress bar and an option to show "details" but these appear to have disappeared in the last few days.
I don't recall switching these features off and there are no settings to restore them, available within the GUI. Is there another way of restoring this functionality?
If not, is a reinstall the way to go? If so what package(s) need re-installing? And in-case it is a configuration script, what files in my home directory need deleting to ensure a clean reinstall.
