Ubuntu Installation :: Security Updates Clobber Configuration Information?
Jan 13, 2010
Why can't Ubuntu store configuration information in a way that it wouldn't need to be clobbered in order to apply security updates? For example, this mornings updates told me I had to choose between using a new version of smb.conf that's part of the security patches, stick with the old version, or let the update installer merge them. Of course, the first two choices have obvious drawbacks: why should I have to choose between losing all my SMB settings or refusing security fixes? So I chose the merge, which came back with "Conflicts found during three-way merge! edit `/etc/samba/smb.conf' and sort them out manually."

I installed ubuntu a few days ago, today I got like 250mb of security updates to I let them run, then restarted, now it keeps running in low graphics mode, everything looks rubbish and I have no desktop effects, the sound has also stopped working. Everything was great prior to this, I was beginning to love the switch from ms to ubuntu. The sound/video are both via hdmi so I am imagining its something to do with the graphics. I would wipe the system and start fresh but it took me so long to get my sound and wireless working.

I've recently installed the unattended-upgrades package on a few Ubuntu 9.04 servers, and it's working great to automatically install security upgrades. However, is there a way to have non-security upgrades automatically installed as well? The README for unattended-upgrades says it'll do security ones only.
My main goal is to have all package upgrades be installed unattended except for kernel and libc upgrades (I want to do those manually on my own time). I guess I could write a script that does 'apt-show-versions -u' to get a list of upgradable packages and then do 'apt-get install' on the packages if their names don't match linux-server, linux-image-server, or libc*, but I was hoping there's an easier way to accomplish this.
I've looked at 'aptitude safe-upgrade -y', but I think that'll install kernel and libc upgrades.

I'm completely new to Ubuntu and only installed yesterday for the first time. The install worked fine. After booting it asked me to install updates. I did this and now when I boot i get:
Gave up waiting for root device. Common Problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough)
- Check root= (did the system wait for the right device)
- Missing modules (cat /proc/modules: ls /dev)
ALERT! /dev/disk/by-uuid/blah blah does not exist. Dropping to a shell Now I've tried searching through the forums and I've seen people with similar problems however none of the solutions suggested to them have worked. The only thing that may work if it is explained to me how to do it is in Grub 2 it is looking for a UUID. Now I tried editing this on startup to /dev/sda5 instead and it loads. Only thing is I read that this is temporary and would have to do it each time which means it's a workaround not a solution. As I explained at the start, first time of using Ubuntu and so far haven't been particularly impressed as I have another problem with the processor being used up by loads of 'udevd

I just installed RPMFusion free and non-free, and now update manager is telling me that it needs to install updates "RPM Fusion (free) Repository Configuration" and "RPM Fusion (non-free) Repository Configuration". When I try to install these I get a message asking 'Do you trust the source of the packages?" and i click 'Yes", it then asks for a password for authentication, and then I get message saying "Could not update packages. Failed to process request" and under more details:

So, it is my understanding that Ubuntu's automatic updates do not install ANY updates that are not "important security updates." For example, it did not upgrade me to Firefox 4 automatically; I had to do it myself (Don't all new browser versions usually contain new security features/patches? Oh well...That is a separate question entirely).
ANYWAY, is there some way to get the latest stable versions of all of my open-source software automatically (or at least all at once, on command), instead of just security updates? It seems silly to have to install new versions for every program manually.
Also, related/side question: Now that I have installed Firefox 4 myself (via apt-get by adding the mozilla-stable PPA), will I stop getting security updates for Firefox through the standard Ubuntu update manager?
Actually, a really thorough explanation of the whole automatic update system (or a link to one) would be great too.

So yesterday I receive a copy of the SANS @RISK security vulnerability newsletter, and, lo and behold, Mozilla's Firefox and Thunderbird are on it yet again. (Yeah, I know, shocking, isn't it?)So I quickly check what versions I have installed. Yup: Vulnerable.I check whether updates are available.These are pretty serious "remote code execution" vulnerabilities and the status is "vendor confirmed, updates available." So why isn't my 9.10 desktop's update manager telling me updates are available?

I'm new to server admin, so my question is based on what may be a bad assumption. With a server, my assumption is "if it ain't broke, don't fix it". In other words, I'm not really interested in upgrading the software to the latest and greatest if I already have stuff working on the server.
However, the one place where I DO want to constantly have upgrades is for security patches. How do I apply security updates to Ubuntu Server... and ONLY security updates?

With an Ubuntu 10.10 upgraded from 10.04, under Software Sources, Updates, there is a radio button marked "Install security updates without confirmation." I have this radio button marked, but still get "Important security updates" almost daily in my update manager. I don't remember this feature actually ever working.

Does anyone know when we'll see Firefox 3.0.19 packaged for 8.04 LTS? I'm still stuck at 3.0.18. And what will happen after this? My understanding is that after .19 Mozilla is dropping support for FF 3.0.
Upgrade policies not withstanding, I find it rather annoying when an "LTS" release doesn't keep up with the most security-critical package in the distro, the browser. 8.04 LTS should have moved to FF 3.5+ a *long* time ago. Now it seems it will be forced to do so or else just forget about browser updates for the last year of 8.04?
I know I can install the current Firefox with ubuntuzilla, I just keep wishing Ubuntu would do it for me.

For some reason Update Manager is not installing updates as of yesterday.I have it set to check daily and notify if updates are available. It has been working without issues for well over a year now.
Update Manager tells me updates are available and presents the list of security, recommended, and other updates. All are selected to update, but when I select Install Updates in Update Manager it returns with a Reading Package Information window overlaid on the main Update Manager window - building dependency tree then reading state information and dumps me back to the main Update Manager window without performing any update actions.

As a matter of routine, I use dd to collect my hard drive master boot records, and I save the resulting file someplace where I can always get to it if I have to. It has occasionally saved me when some kind of disaster has struck and damaged a partition table or rendered a drive unbootable.Since I have switched to a fully encrypted system, I have been wondering exactly how to save the dmcrypt information. Dmcrypt works with a standard filesystem, and the filesystem itself isn't encrypted, only the contents.Thus dmcrypt must write a header someplace that includes all the information needed to decrypt the contents of the partition, including the key and the type of encryption employed.
Should something happen that causes that header to become corrupted, the entire partition is inaccessible and no recovery tool will work. So, it would seem like a really good idea to use dd to copy that header someplace safe.Now, I haven't taken the time to sit down, read the dmcrypt code, and try to figure out how to do it from that. The command cryptsetup luksDump doesn't do what I want because it dumps that information, but not in a format that would be immediately useful in copying the information back to a damaged partition. And every howto I've found tells me how to set up dmcrypt, and encrypt partitions and so forth. None tell me how to recover this information, other than mentioning that it is stored in the first few sectors of the partition.
Looking at some of this through a hex editor, I *think* that saving the first 512 bytes of the partition gives me what I want, but I'm not positive of that and I hesitate to depend on any putative backup scheme of this sort that I haven't vetted. I want to save no more than I need, and I certainly don't want to save any less than what I need.Edit: As I think about it, the first 512 bytes can't be enough because Luks/dmcrypt permits multiple keys. So how much information do I need to save?

We've had a site broken into, and several of the desktop computers physically stolen. The Ubuntu 9.10 router/gateway/firewall/web filter box has however NOT been stolen. I'm wondering if there is any information we can get from this that would help the police.
NAT and firewalling are handled by firehol. It runs a DHCP server to provide the desktops with IP addresses. It runs a Samba server with some file shares. It runs Squid and Dansguardian in an intercepting-proxy configuration. Of particular interest might be whether the MAC addresses of the stolen desktops can be obtained, which might help with tracking them down. Also anything to narrow down the time of the break-in.

I've been looking for a tweak that would allow me to store temp and log files in ram. I've found a few that involved editing the fstab file, but they were either Ubuntu articles or they were over a year old and perhaps didn't apply to Fedora 14.I hear there is also a 'noatime' command that can help speed up processes by telling the kernel not to saved when files are accessed.And what are the advantages and disadvantages of noatime, and writing log/tmp files to ram?

This may be a stupid (?) question, but does any one know of a patch for sudo that allows the sudoers information to be pulled from mySQL?
I run multiple servers with multiple people working on them and would like a one-stop update of permissions.
Yes, I could use rsync or the like, but I'm just wondering if this has been done, or could be done.
(Sorry if this is the wrong forum, I'm kinda new around here, posting wise and this seemed to fit. Feel free to move it if it's not)

i recently started sockets programming. In the process i began to look for relevant network information about my computer and realized that ifconfig wasn't displaying the same information that resides in my /etc/network/interfaces file. On the interfaces file my IP address is 192.168.1.109 for interface eth0 but ifconfig displays 192.168.1.101. I was under the impression that ifconfig got its information from the interfaces file but clearly doesn't. I tried re configuring the device with ifconfig and then disabling and re enabling the device with ifdown and ifup so that the device updated its information but it didn't.
