Ubuntu Installation :: Sources List File And Apt-Get Update Not Working
Jun 6, 2010
I am using ubuntu 9.10. Can any one check my /etc/apt/sources.list file and let me know if anything wrong in the file. Sudo apt-get update is not working, there are some packages which are failing.
I have updated from 9.10 to 10.04 on line via Update Manager. Update Manager messed up my sources. Blocked most of them on update. I unblicked them and changed everything to Lucid from Karmic. No luck. Errors all the time:
Code: W: GPG error: [URL] lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 W: GPG error: [URL] Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 W: GPG error: [URL] Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 I cannot add gpg keys and use for example canonical.
In my netbook /etc/apt/sources.list contains the cdrom asdeb cdrom:[Ubuntu ....]/hardy main restrictedIf I keep the iso file in /ubuntu and then want it to be refreshed during #/etc/apt/apt-get updatehow must I motify /etc/apt/sources.list
how to unlock my sources.list file, so I can add code and upgrade Firefox 3.53 to 3.6?Ubuntu 9.10Forget it...I tried again, and it saved my source code...
I am running Jolicloud on my netbook (which I believe is an Ubuntu derivative) and I am tried to enter the getdeb.net sources in so I can install apps from the website through APT but
1) When I entered the sources into sources.list and then the key into Terminal and then went to the site and tried to install an app it didn't work.
2) I deleted the line of code in the sources.list file and when I opened terminal and entered "sudo apt-get update" it showed the list of sources, but on the list were Getdeb.net sources.
My question is how do I delete sources that aren't in /etc/apt/sources.list ?
I tried to change the basic toolbar to cairo dock,a tutorial that i found told me to write in terminal gksu gedit /etc/apt/sources.list.d/winehq.listso i write it and a window opened,i couled not find the text that told me(the tutorial i mean)so i closed the window,after that i keep taiking the same error
E: Type �sudo� is not known on line 55 in source list /etc/apt/sources.list E: The list of sources could not be read. Go to the repository dialogue to correct the problem. E: _cache->open() failed, please report.
now whene i got in the winehq.list the text has gone and i take this error in update manager,my software center doesn't work and my terminal whenever i type sudo commands says
E: Type �sudo� is not known on line 55 in source list /etc/apt/sources.list
I've got the following problem: I just noticed that there were just very few notifications about updating the system (usually there are damn many of them in a week) So I opened the update manager and clicked on "refresh list". The following result popped up: p,li{white-space:pre-wrap;}E: Error http://ppa.launchpad.net natty/main/Sources Sources 404 Not Found First I thought, it would be just some kind of server problem, but it didn't stop. The next thing was to research the thread and I even found something. However, the solution suggested didn't work at all. (Things, which might have caused this: I installed the default software center |I'm using Kubuntu, but in this case that fact doesn't matter| and used it. To sum up:
- not able to update the system referring to the launchpad main sources for 11.04 - following error: E: Error http://ppa.launchpad.net natty/main/Sources Sources 404 Not Found It would be great if this was a common issue and I've been simply too stupid to find a proper solution. So you could just post the link.
I just installed Debian 6.0 using the large installation image and a KDE environment now I am having issues setting up my sources.list file so that I can get all my updates over the internet. My current sources.list file looks like this:
# # deb cdrom:[Debian GNU/Linux 6.0.0 _Squeeze_ - Official amd64 DVD Binary-1 20110205-18:15]/ squeeze contrib main
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!
Today I decided to include again Debian Volatile and discovered that it doesn't exist anymore and that I can get the same packages using this line: deb [url] squeeze-updates main
And the first question is: is this the same than debian-security?
Then, I decided to use [url] to make things less confused, and this was the output:
The first line is Ok. The second line, I guest it's the same than my second line. But, the third, is something different. So, the main question is: what is the difference between squeeze-proposed-updates and squeeze-updates? Are those repos completely separated from squeeze/updates (in security.debian.org)? And, what else should I add to have an always up-to-date and secure system?
It's always a good to backup a configuration file like sources.list before you edit it. To do so, issue the following command: sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup Where does it backup to and how do I access it? I want to put the backup on removable disk or upload it
The PowerPC does no longer receive commercial support form Canonical. How do I update /etc/apt/sources.list. My goal is to change deb [url]... to [url], using find and replace.
Found something at [url], oh no false alarm! This thread does not explain how to change the /etc/apt/source.list either. I know what to change but do not know how.
Appear sometimes ago a message: E: Opening /etc/apt/sources.list - ifstream::ifstream (13: Permission denied) I'm trying update my computers but I don't get.. Please.. All my docs, movies and pictures are in this PC... What Can I Do to fix?
I am developing a customization of ubuntu for my company, as we mirror ubuntu repositories it would be great that the distro's sources.list be configured for using our repos instead of ubuntu's official on install, without the need of me going PC by PC making such configuration myself... How could this be achieved? Is there documentation about it? I have only managed to find data on how to configure the sources.list after installation.
I am installing a hp officejet pro 8500 all in one printer to knoppix 6.0.1. install hangs saying i need to disable cd sources in etc/apt/source.list. How do i do this?
When I exit from Synaptic I get a list of duplicate sources. Is there a program that remove them? Often I can not spot the duplicates in the software sources window.
But when I look in my sources.list, the PPA repository is not there. Nevertheless I SUSPECT I'm receiving it's updates.Is there a file that PPAs are being written to other than sources.list?Should I manually update sources.list in order to add this PPAs?
I was trying to install Tor and deleted a couple lines out of the sources.list. I think I may have deleted something I wasn't supposed to. When I try to run the Update Manager I get "An unresolvable problem occurred while initializing the package information.report this bug against the 'update-manager' package and include the following error message: 'E:Malformed line 56 in source list /etc/apt/sources.list (dist), E:The list of sources could not be read.'" How can I fix this?
There is a problem with my source list (apparently) I'm running 11.04 if that helps.When I try to use apt-get install update for example, I get: "Malformed line 59 in source list etc/apt/sources.list"The same error occurs when trying to access synaptic package manager, it tells me there is a malformed line and the list of sources cannot be read.This error prevents me from apt-getting anything, updating and i suspect it is affecting the software center too.
I have added to Debian Wheezy testing repositories. After a restart there is no desktop anymore just the wallpaper picture is visible but no desktop pop-ups.
When I want to install the desktop through recovery mode, I get an error message that it "can't fetch...repos". How I can repair /etc/apt/sources.list through recovery mode?
