Ubuntu Networking :: Update Manager Behind Proxy Not Working In 10.10?
Dec 10, 2010
I was having trouble getting update-manager to work behind a proxy (without authentication). I tried everything I could find in my search, including setting http_proxy environment variable, setting the System->Preferences->Network Proxy and setting the Synaptic package manager proxy settings. Nothing seemed to work.
It turns out that the problem was that the System->Preferences->Network Proxy allows "automatic" proxy (pac file), and I had used that. update-manager doesn't do anything with this setting I guess. I changed from the automatic setting to a host/port manual setting and it began working.
I suspect this qualifies as a bug. update-manager should do something more reasonable than quietly fail if the settings are for automatic - it would be really nice if it worked, and if not then an error message.
As the title says i updated my system which then needed a reboot. I also installed Mixxx djing software to try it out. So i thought id just restart the system. Usually when i boot into my desktop wireless automatically can connect to my router but not this time, wired only for now... i know theres tons of wireless issue threads but some more experienced users will be able to get straight to the point and run through some diagnostics with me.
It started with Update Manager constantly recycling and not updating. When it starts it shows 295 files and 308MB waiting to download. When I click on 'Install Updates' it appears to go through the process, and then presents me with the same 'waiting to install' window again - and again, and again - in fact as many times as I care to click the 'Install Updates' button. No error messages appear. The 'Settings' button produces the same apparent process as the 'Install Updates' button, but doesn't present me with any other screen.
I've tried all the solutions I could find on these forums and nothing works. The sudo suggestions for Terminal usually produce error codes. adjusting a line in the 'hosts' file. When I tried this I was presented with the obstacle of not having access to the read-only file, and no matter how much I searched I couldn't find how to gain access . While investigating all these possible solutions, I was directed in turn to the Software Sources and Synaptic Package Manager applications, but when I attempted to start them, 'Starting Administrative Application' appeared briefly on the taskbar - and then disappeared!
Now able to connect to the internet with Mozilla Firefox. Package Updater still not receiving updates....Opened Terminal window and logged in as root: Added following to the yum.conf file:
Update manager on my computer (running ubuntu 10.04) isn't working. I can open it up from the System menu, but when I press "check" or "Install updates" it the cursor just spins in circles like it's thinking but it never does anything. I can't even quit the program.
I recently did two things that might have caused the problem.
1) I upgraded yesterday from 8.04 to 10.04. I don't remember if I ran Upgrade Manager or not earlier today but I think I might have.
2) I have a dual-boot system and I re-partitioned my hard drive this evening. I shrunk the partition with Ubuntu on it, moved the swap partition over, and expanded the Windows partition. The first time I logged in after re-partitioning the hard drive I got an information message saying that the Update manager hadn't loaded correctly. That was when I first noticed the problem, so I suspect that it has something to do with me moving around files in the re-partitioning.
I recently tried to add a repository by following the directions here: Banshee.fm/download and then select the ubuntu icon at the top. Here is the error I get when I try to run update manager: "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 'banshee-team/ppa/ubuntu' is not known on line 1 in source list /etc/apt/sources.list.d/banshee-team-ppa-natty.list'The command I entered was sudo add-apt-repository ppa:banshee-team/ppa. I have tried to remove all banshee related checks in software sources of the ubuntu software center. Then I just removed the lines all together. I still cannot open update manger. Get the same error. Anyone know of a fix?
I'm having an issue on multiple Lucid boxes where I can't get proxy ARP to work. This is to be used in conjunction with openswan IPSec. I've enabled forwarding and disabled sending/accepting ICMP redirects for each interface as per openswan's requirements. I've added the proxy arp lines for all, default, eth0, and lo to sysctl.conf:
Code: net.ipv4.conf.eth0.proxy_arp = 1
I then connect the IPSec client, and I have connectivity to the server. When I try to ping (or otherwise access) something else on its subnet, I reach the intended target, but then it ARPs for the sending machine, and the Ubuntu server doesn't respond to the ARP.
I have an ARP entry that looks like this, added via arp -s 192.168.254.100 -D eth0 -i eth0 pub:
Address: 192.168.254.100 (the correct virtual IP for the client) HWtype: * HWaddress: <from_interface> Flags Mask: MP Iface: eth0
Best I can tell, everything is in order... I can listen in with wireshark on the server and see that it's receiving the ARPs, but I can't get it to respond to them.
this happened to me before, where when I try to open Software Center, Synaptic package manager, or update manager, it would freeze with the window open and I would have to force it to shut down. I decided to re-install the OS after this happened and I just updated ubuntu and it is happening again.
I tried to install emergent using following guide:[URL](Ubuntu) However, I did not succeed, it seems that it could not install emergent properly. My far worse problem now is that it messed up my software center and update manager. I get following error message when starting the software-center:
Code:

I want to use PAC file as I work with multiple networks. But this is not working for me. Following is the code of my pac file. Can someone tell me what's wrong with it?
Code: function FindProxyForURL(url, host) { if (isInNet(myIpAddress(), "10.6.0.0", "255.255.0.0")) { return "PROXY myproxy:port"; } return "DIRECT" ; } Browser I use Firefox and platform Ubuntu.
I am having issues with Update Manager after cancelling an Update.The Update Manager shows a number of required updates, but when I click on Install Updates... Nothing happensWhen I launch sudo dpkg --configure -a in a terminal I receive the following message:dpkg: status database area is locked by another process.On another forum i saw something regarding a gksu.lock file that needed to be deleted... but I can't find any such file....If I try to launch update manager via a terminal: sudo update-manager I get the following error:
requiredDownload could not be calculated: E:Unable to parse package file /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_karmic-updates_main_binary-amd64_Packages (2), E:Unable to parse package file /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_karmic-updates_main_binary-amd64_Packages (1), E:Unable to parse package file /var/lib/apt/lists
Ubuntu 10.04 64 bit I have not been able to update using the update manager or by using the package manager. It seems when the update manager tries to download all the requests fail.Anyone else had this problem??
I have been looking around the forums searching for similar problems, it seems not only me had this problem. About a month ago I did a regular update via Upd Manager. The next day - no wired connection.Still managable, since the local library has wireless. Now that won't work either.Just after I upgraded from Jaunty, I accidentally removed NetwMngr from the top right corner of the screen, but that should not have anything to do with how the program works, right? I now cannot reach NM, if I run it from the terminal, nothing happens visibly.
I used Ubuntu for the first time yesterday (V.9.04) and imediatly upgrade it to V.9.10. After,the DSL conection failed to conect. After reading many threads here I was able to connect by opening a terminal:
sudo pon dsl-provider
It seems ther's a bug with network-manager, but I'd like to use it again as it easier and NB user-friendly.
Arg, I just removed the bad update 2. 6.35-24.now update manager wants me to install new ones; is it still the 'bad' update that messed up my wifi or has it been fixed?
Writing this from a 9.10 LiveCD, so I know that my hardware is working fine.My system is running 10.10 normally. Last night, the update manager popped up, as it frequently does, and said I had some packages that could be updated. So I let it update after which it said I needed to reboot. So I did, and now it doesn't recognize my network connection, and even the blinky lights on the port itself stay dark. don't know a lot about networking or stuff under the hood, but I can work a console and/or text editor if someone can tell me where to look and what to type.My hardware is (from "lspci | grep -i eth"):02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)The packages that have a modified date of last night are:
Using Ubuntu 10.04 (2.6.32-31)on a Dell studio today.Update manager offered four updates, one about networking. I accepted. After restart the Network-Manager icon had vanished from the tool bar and was replaced by a second loudspeaker control icon. No ability to link to the internet. Starting Network-Manager from the pull-down menus did not help.Muggins Noob thought, un/re-install Network Manager. Duh! Uninstall is fine, but re-installing from the web without Network-Manager, tricky. Sadly no ethernet wire available, either wifi or GSM/3G.
Currently my DHCP Server is working now what i want to have is auto detection of squid proxy in any browser but I still got an error in my dhcp server when I restart it.
My Config:

downloaded wubi 10.04 & after install wireless inop. 64bit 10.04 & unable to connect with a cat5 to download fixes My problem is finding the fix for wireless & downloading it with windows. So how can i download the fix in windows & install with the update manager or whatever. Bottom line what is the fix & how can i download it with windows?
I can open Update Manager fine and it runs though it's little gambit of "Building data structures" etc...
Up at the top it says "The package information was last updated 13 hours ago."
Before I updated to Natty I used to be able to just click on the "Check" button and it would prompt me for my password and then check for updates.
Now if I click the "Check" button it goes grey for a bit, never asks me for my password and then just comes back up with the same "The package information was last updated 13 hours ago." message.
However, if I actually load up the terminal and type out "sudo apt-get update" then go back and load the Update Manager again it will say "The package information was last updated less than one hour ago." which is what should be happening when I click the "Check" button.
I've tried deleting my lists but this didn't resolve the issue. Any clue what else could be happening here?
I also noticed that I had some updates available when I loaded Synaptic Package Manager that didn't show up when i loaded the Update Manager.
I've also tried re-installing update-manager. I've gone as far as to do a complete removal and installed it again. Still not working right.
I think it has something to do with the fact that it's not prompting me for my password like it used to...
cc -pipe -Wall -DOPENSSL -O2 -g3 -ggdb -c -o md5.o md5.c md5.c:20:25: error: openssl/md5.h: No such file or directory md5.c: In function md5_mac: md5.c:28: error: MD5_CTX undeclared (first use in this function) md5.c:28: error: (Each undeclared identifier is reported only once md5.c:28: error: for each function it appears in.)
[Code].....
Running Ubuntu 9.10 (i386) with latest patches from update manager. If I try using the 4.2 archive I get the same result.
I have similar problems with aircrack-ng suite, but I'll leave that until later!
I recently installed Ubuntu 9.04 off of a disc and it worked perfectly, however after I downloaded and installed the system updates from the update manager, it stopped working and it won't even see my device. I have a Zonenet ZEW2500 USB wireless adapter.
I just did a dist upgrade on two computers. One of them was fine with the network manager, but the other, netbook, now refuses to start the service. If I do service start network-manager I'll get a message saying a process started, but it must be immediately dying since I can't find the pid or any network manager processes at all. I looked at daemon.log and noticed it was complaining about nm-system-settings.cfg not being there. One question I have is how is this not getting generated? It's not in the deb so somehow it must be generated. I put a fake file in there and even put some data from a pastebin I found online that looked promising, and the message in daemon.log went away but the pids were still dropping off.
I have many problems with nm-applet, but I don't want to go into it so much now that the service can't start. The problem I do see popping up is something like: ** (nm-applet:2622): WARNING **: <WARN> applet_dbus_manager_start_service(): Could not acquire the NetworkManagerUserSettings service. Message: 'Connection ":1.24" is not allowed to own the service "org.freedesktop.NetworkManagerUserSettings" due to security policies in the configuration file' (had to pull message from online, don't remember the exact message) I've tried installing and reinstalling, doing a purge uninstall. Next thing I was going to try is an aptitude uninstall of all of the dependencies in case something got weird in the upgrade.
