when i log into my server, I see the following message

Welcome to Ubuntu 12.04.4 LTS (GNU/Linux 2.6.38-15-generic x86_64)

 * Documentation:  https://help.ubuntu.com/

0 packages can be updated.
0 updates are security updates.

New release '12.10' available.
Run 'do-release-upgrade' to upgrade to it.

But then when I run sudo do-release-upgrade i get this message:

Checking for a new Ubuntu release
No new release found

Doesn't that seem kinda silly? I was thinking that I should upgrade to version 13.04 or even 14.04 to be more up-to-date, but like this I am kinda stuck.

I have seen this post: Why is "No new release found" when upgrading from a LTS to the next?

But that was answered back in 2012, I would think that the new version is available for upgrade now?

Thanks!

I just upgraded my ubuntu server via command line to version 12.04. I was on 11.10, so when I upgraded I have to switch the sources in source.list to the old-releases.ubuntu.com source. Everything worked fine.

Anyway, now I want to upgrade again, but the problem is my server is having a problem contacted the us.archive.ubuntu.com server. When I do apt-get update I get many errors that look like this:

W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-security/universe/i18n/Translation-en  Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)

Pinging us.archive.ubuntu.com doesn't work with unknown host error. I also tried ping google.com and it didn't work either. Pinging 8.8.8.8 however did work. So I am wondering what has happened. I was poking around the web and it seems like its a DNS issue, but I don't know what to do. My /etc/resolv.conf file is blank.

Does anyone know how I can fix this issue?

I have a home server that I need to access via remote desktop, and I want to leave the server there without a monitor hooked up to it. Everyday the server turns off and turns back on. There is no monitor installed.

I find that my 12.04 64 bit installation, when booted without the monitor plugged in, just hangs on a screen that says the system will start in low-resolution mode. It never actually starts up the desktop environment, which is what I need. So it is impossible for me to remote desktop to the server after it is started. This is the problem.

When I reboot with a monitor installed, the desktop session starts and everything is fine.

Is there a way I can configure the system to run the desktop session after every boot without a monitor installed?

I have looked around the net quite a bit. This question mentions that the desired behavior worked in 12.04, but I do NOT have this experience.

Any help is greatly appreciated!

I am logged into a remote ubuntu server, and I accidentally erased the entire /home/username/ directory for the current user. The only thing left is a hidden directory called .gvfs. I don't need anything of the Documents/Music/etc.

Now it is not letting me cd into the /var/www/ directory, which has permissions 666 and it is owned by the current user.

I am afraid to disconnect from my ssh session because I don't know if I will be able to get back on. Have I permanently created a problem? Is there a way I can replace the most important files to the /home/username/ directory?

Thanks!

** EDIT **

Thanks everyone for the help. I figured the problem with cd into the /var/www/ was actually my permissions in the /var/www/ directory. It was set to 666, changed it to 755 and everything was good again. It doesn't look like anything systematic was ruined by deleting the contents of the user folder.

I have already installed MySQL workbench from the Software Center on a recent installation of Ubuntu 12.10 (32 bit) with no problems. Since then, I just installed ubuntu 12.04 LTS on another machine (64 bit) and I can't find it in the software center.

Is there a way I can enable the repositories to make it available to me? I know it exists for 12.10 so I am assuming it is available for 12.04.

Thanks for any input!

UPDATE

I switch my server in the software sources GUI (from Ubuntu Software Center go to Edit -> Software Sources..)

I was set to the Spain server (since I am in Spain) and I switched it to the Main Server, then did apt-get update and i was able to install with apt-get after that.

I just installed the new ubuntu 12.10. I also installed the Compiz Settings Manager because I like to customize the desktop a little bit. I really like the window switcher that used to come with Compiz. With this setting, you can customize a key-combination (I like to use the Super + Tab) and you can cycle through all the open windows that you have. It is a cool 3D visualization and very useful. I think it was called "Ring switcher" in my 12.04 installation.

Does anyone know how I can get this functionality back?

Thanks!

I often work remotely. I use the Network Manager to set up my VPN connection, which has worked pretty well. The VPN I have set up currently using the Password with Certificates (TLS) type. What I want to do is only route certain traffic through the VPN, and all other traffic over the normal local internet connection.
Is this possible?

Just to help explain my situation I will give an example of the type of connections I usually have to make with the VPN network. We have an "intranet" web site set up on our work network, so this web site is only accessible to me when I use VPN, but is accessed the same way I access other sites, like Google or askubuntu.com. I often connect to a desktop computer over the VPN connection via remote desktop, where I enter the name )IP Address) of the desktop computer, username, and password. I connect to a MySQL server using MySQL Workbench, where you enter an IP address, username and password. I often connect to linux servers using SSH.

For all of the above connections I need the VPN. However I also do some normal web surfing, as well as connecting to resources outside of the work network (Gmail, Stack Overflow, Gaming, etc.). For these connections I wish not to access via the VPN connection because these connections do not need my VPN, the VPN just makes this much slower.

I have tried the technique describe in this link: http://darrenwatt.com/split-tunnel-ubuntu/

This did not seem to work for me. Specifically, I couldn't connect to the "intranet" site after checking the "Use this connection only for resource on its network" check box and connection the VPN.

Does anyone know how I can selectively route traffic through the VPN? Does this make sense?

Thanks!!

I have a fresh installation of Ubuntu 12.04, I have been running it for about a week. Suddenly today I noticed my computer freezes every 5 seconds. I restarted the computer and I still get this. I believe it is a process called watchdog/0 that is using all the resources. See the attached pictures.

How can I stop this? I can barely use my computer like this.

UPDATE

Well I just did a cold reboot, (shutdown, unplug, and plug back in, and turn on) and it seems to have fixed it. After looking at the man page for watchdog, it seems that this process may stay on during a restart? so it is more like a soft restart? Why that happens I don't know.

I just tried to set up evolution with the MAPI plugin to connect to my Exchange Server 2007, as is described in this link -> https://www.linux.com/learn/tutorials/370590-connect-evolution-to-an-exchange-server.

this is did not perform very well, it kept freezing and could not send a message, although it did retrieve a lot of info from the server, it just wasn't doing the job.

I am going to try Thunderbird now, with SMPT. Maybe it will work.

What have you all had the best luck with, as far as an email client for Microsoft exchange server 2007?

Thanks a lot!!

** UPDATE **

So I set up Thunderbird. The setup wizard automatically detected my server settings and this worked well for retrieving the information from the server (like inbox and custom folders). The sending didn't work by at first. There was a problem with the SMTP authentication. I tried each authentication method until I was successful sending a message. The one that worked was NTLM.

Thanks for the good tips for this problem!

** UPDATE **

It has been a few days using Thunderbird. It seemed like it was working at first, but now I see that it is not performing very well. Every time the program runs, it hangs on "bringing inbox up to date". Also when you first open the program, it seems to retrieve the new email messages correctly, but after the program is opened, it hangs and will not get new messages that have been sent since opening the program... back to the drawing board.

I noticed that Remmina Remote Desktop comes installed by default in 12.04. This is great because I have used it in the past and really enjoy it. Anyways, there is a little problem. When I am doing RDP connection to my Windows 7 machine, it seems that windows shortcuts are enabled by default, without pressing ctrl or alt or the windows button. Every time I type the letter "f", the search window pops up in the windows environment, and the text "f" is never entered into the email. As you could see, writing an email or editing other text is almost impossible like this.

Has anybody had any experience with this? Know how to fix it?

I have a pretty generic USB webcam (it is a generic sphere shaped webcam i got from IBM, it says IBM on it) that I want to work with skype. In past installations of ubuntu, I could get this webcam working with skype by using this command (or something very similar to it)

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

I have a fresh installation of Ubuntu 12.04, and I just installed Skype for Linux beta 2.2 through the APT software center. Needless to say when I plug in the web cam and use skype, i cannot get video working. I already have this web cam working with gmail video chat.

When I execute the above line of code to start skype, i get this output:

ERROR: ld.so: object '/usr/lib/libv4l/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored.

And then skype starts up and works like normal, but when I try to test or use the web cam nothing happens, no error but no video.

In the skype options: Video Devices tab, it says that it finds a PC Camera at /dev/video0. When I click "Test" i still just get a black screen and no light on the web cam.

2 questions:

How do I use Ubuntu to tell the model and driver for the web cam, so I can troubleshoot easier?

Does anyone know off the top of their heads how to fix this problem?

Thanks a lot!

Long time ubuntu user here. I usually use www.ubuntuforums.org but i thought I would something here. Anyway i recently upgraded to Ubuntu 12.04 with my Lenovo x61s laptop. Immediately after starting up, i noticed that the wireless connection drops and forgets the wireless keys about every 10 to 15 seconds. So every time i finish entering the wireless password, i can wait 10 seconds, and I get booted from the network and am prompted again for the pass phrase. Obviously there is a problem here, and I have noticed a lot of other questions on this forum about this. The only real answer I saw was doing:

sudo iwconfig wlan0 power off

But when I do that I get this error:

Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan0 ; operation not supported.

And i know my wireless card is using wlan0 for the connection.

Please any help is greatly appreciated!

** EDIT **

I just restarted the new install for the first time, and now I am on a different wifi network, and the wireless connection seems to be working. Will update with any changes.

** UPDATE **

So last night I shut down the computer and brought it home. The wireless performed flawlessly on my home network. I brought it back to the office, where i had the original problems, and still i get kicked off the wireless network every 15 seconds... It must be a problem with the network instead of with Ubuntu. Thanks for the help everyone! but I think my Ubuntu installation is working correctly!

Here is the output from lspci -vv for the wireless controller:
