CentOS 5 :: How To Prevent Update From 5.3 To 5.4
Oct 23, 2009
when I am doing a "yum update" I receive now a long list (~94MB) because of the latest CentOS 5.4 release.I am running CentOS 5.3 on a virtual machine (virtuozzo) and had already problems to install 5.3 before. To not lose the installation I do not want to update to 5.4 but of course I want to get all updates for 5.3.How can I configure my CentOS 5.3 to update the server only with 5.3 patches/releases and how to prevent it to update to 5.4?

The server runs# uname -r2.6.18-128.4.1.el5However, today I executed yum update kernel*due to security advisory. I was just about to reboot the system when I realized that it runs VMWare Server Instance that will most likely fail to restart after kernel upgrade (I had a hard time fixing it after previous kernel update). Now I want to keep 2.6.18-128.4.1.el5 after reboot.I see that new kernel is scheduled for booting:
# cat /etc/grub.conf
default=0
timeout=20
[code]....

I don't want games on my computer (running 9.10). Removed them successfully, but update manager keeps presenting them as suggested updates in update manager. Requires me to go through and uncheck all the games each time I do an update. Is there some way I can stop update manager from re-presenting removed programs or block future game updates?

I've recently downgraded kaffeine to 0.8.8 to get back the EPG which was working under hardy. Is there a simple way to prevent a package from updating when I update the rest of the system? I realise that this is not normally a good idea to keep packages back like this, but the upgrade to kaffeine caused the loss of a useful tool.

A few days ago I had a problem with my screen resolution after a safe-upgrade. I struggled a little but I finally downgraded and pinned the intel driver. But now, each time I turn my computer on I get a notification of "1 update aviable" I've checked and the update is correctly pinned (I used keep and forbid-version), it does not upgrade. As you can see, this is not critical, but I would apreciate a fix.
Details:
Debian sqeeze/sid with KDE4 on Acer Aspire One ZG5. I manage my programs with aptitude.

I have recently upgraded ubuntu to natty. I'm using a ppa (Firefox Stable) and during an update using update manager it blocked on these lines:
Setting up xulrunner-1.9.1 (1.9.1.18~hg20110309r27352+nobinonly-
0ubuntu1~umd1)
This prevents me to even see other updates cause update manager says the index is broken. How can I solve this? I don't want to reinstall firefox because I'm worried it blocks again (now firefox works).

One of my machines is a desktop with a WIFI connection. This machine is not configured to use NetworkManager; instead, it still does things the old way via /etc/sysconfig config files.
Problem: this WIFI connection requires wpa_supplicant. By default, F11 brings up the network at priority 10 and wpa_supplicant at priority 23. So dhclient fails its initial attempt to obtain an IP for wlan0 (it will retry and succeed but by then it's too late). This causes other network-related startup tasks to fail. For example, ntpdate fails. This is problematic for systems with faulty CMOS clock batteries since ntpd will reject updates if the clock skew exceeds some threshhold (so ntpdate is usually used to preset the clock).
The workaround is easy enough: add "Required-Start: wpa_supplicant" dependency to the init stanza in /etc/init.d/network and let chkconfig figure out how to rearrange the priorities. This ensures that wlan0 is actually capable of sending a DHCP request when dhclient starts.
This works fine...until yum update decides to replace the scripts in /etc/init.d and, consequently, things go back to the old, broken startup priorities.
So my question: Can yum be told to not change files in /etc/init.d that have been modified by the administrator? Or to at least not overwrite the LSB-style init stanza in those files?
Alternatively, is there a better way to do this that's not vulnerable to updates? I tried playing with the modprobe.conf "install" option to pre-start wpa_supplicant before wlan0 comes up but that has so far been unsuccessful.

After install glibc-2.10.1-4 (x86_64) package, i couldn't run the qemu-kvm anymore.
SELinux is preventing qemu-kvm (svirt_t) "setrlimit" svirt_t.

I need to prevent that the latest kernel update removes the only kernel that still works in my computer. how can i do this? Currently I have 3 linux kernels versions:
Code:
Ubuntu 10.04 LTS, kernel 2.6.32-23-generic
Ubuntu 10.04 LTS, kernel 2.6.32-23-generic (recovery mode)
Ubuntu 10.04 LTS, kernel 2.6.32-22-generic
[code]...
But only the oldest works. With the new update there is a new kernel version (2.6.32-24) that possibly will not boot (like previous 2.6.32-* kernels) and also I expect that, as in previous updates, the oldest kernel will become inaccessible, thus rendering my ubuntu unbootable.
PS: unsolved threads on the underlaying problem: Can't boot default kernel after upgrading from 9.xx to 10.04 lucid Upgrade to 10.04 freezes on the Ubuntu screen

I installed CentOS 5.2 because I want to install the latest VMWare Server (2.0.1).The release notes of vmware server say: "Support for CentOS 5.2".But after installing CentOS 5.2 and updating the packages marked for update,the Version of the system is 5.3. I know from Debian that if you do not explicitly want to do a system version upgrade,only bug fixes and security fixes are installed. That seems to be different with CentOS/RHEL?
Is there any way (or what ist the right way) to prevent automatic upgrade from one release to another? I don't want VMWare Server to stop working because of some upgrade from 5.x to 5.y.

How can I prevent users from changing their own password? I was surprisingly unsuccessfull in finding a solution for this on google. Lots of stuff about hardening ssh access or dealing with password aging using "chage" but nowhere could I find an answer for my question.

We are currently troubleshooting the following error, which was repeatedly being displayed on the console:
kernel: Northbridge Error, node 2<0>K8 ECC error."
After replacing all of the memory, the error remained, so we tried updating to the latest kernel. (Currently having to use centos-plus because we are using XFS)
After the kernel update the error disappeared fro 5 days (previously UNHEARD of - would often repeat several times a day), it appeared again and hasn't appeared since.
It does not seem like any real damage is done here - and I would like to suppress this error somehow. Optimally I would like it to only be forwarded to the log files - and NOT be displayed on the console.
Could someone point me to an easy way to set that up?

I am trying to prevent the dm_mod and friends from loading during install.I am installing by PXE boot with NFS and kickstart files over http. This works fine for other machines.Ok, I have a Dell PowerEdge 2900 III with 8gig ram, PERC 6/i raid controller.The raid has 8 1TB drives in it, so the total size of the device is >2TB.There is also an SATA drive, which is NOT on the raid controller.
The problem is, I want to install CentOS on the SATA drive. The SATA drive comes up as a device-mapper drive, with a big crazy device name.This is ok, but the problem is, when the system goes to boot, it just says 'missing operating system'.I can't boot from the raid because it is large enough to require a GPT partition, and CentOS says it can't boot from a GPT partition.The SATA drive would work FINE if I could just prevent the damn device mapper from loading, so that I could install on the SATA drive in ordinary SATA mode.
I have tried re-squashing the stage2.img with /etc/modprobe.conf with alias dm_mod off and such, no luck.I also tried adding an /etc/modprobe.d/blacklist file, that did not work either.I also tried putting blacklist= dm_mod in the kickstart file, but that seems to be a fedora-only option and it kills my install. any ideas on preventing the dm_mod et. al. from loading at install time??

On two Centos5 servers, yum gives a segmentation fault error when trying 'yum update' or 'yum check-update' after running 'yum clean' :
[Code]....
The error is the same for the other computer except while attempting to update the rpmforge repository. Nothing has really changed on the servers in some time and 'yum update' worked fine on each yesterday and I have no idea why they would both suddenly fail!

For some reason, when I do a yum check-update I get a list of no changed packages to install. If I follow this immediately with a yum update then it tries to install drbd83. I've tried a yum clean all and repeated the commands and get the same thing. This happens on both the machines that are set up to use DRBD. Just seems weird and I don't understand. Anyone got an explanation?

Just checking to be sure. 5.3>5.4 update went without a hitch:) But a message ran about (/etc/yum.repo.d) CentOS-Base.repo.rpmnew. Comparing CentOS-Base.repo with the new one show the 1st has the correct priorities and .rpmnew does not have the correct priorities. Should I remove the *.rpmnew repo after making sure it otherwise is the same as the original CentOS-Base.repo?

I am an old days RH release user(from 6.x) and just switching back from Debian/Ubuntu to CentOS on some servers, but I can not understand the kernel update strategy currently enabled in CentOS.There are two boxes, with almost identical installation, but recently there was an auto update of kernel on one box. This auto update also seems to issue an auto reboot on the machine, which is unacceptable on server machines.

After some testing for a couple of days, I decided to take the plunge and update all my 5.3 machines. Using the recipe from the release notes:
yum clean all
yum update glibc*
yum update yum* rpm* python*
yum clean all
yum update
shutdown -r now
I updated some guinea pigs that I had physical access to and didn't have any issues. So I remotely updated a small farm of LAMP machines that handle a couple of million page views per day. It took each machine approximately 5-6 minutes to download/install/reboot.

I just ran a "yum update" on my CentOS 5.3 system. After a reboot, I noticed /etc/redhat-release show CentOS 5.4.
I thought yum upgrade was supposed to do that?
I wanted to simply patch my CentOS 5.3 system without turning it into CentOS 5.4 ... YET.

I have Centos 5.3 on our server When I log-in in webmin I have a message "Warning - Your system is actually running CentOS Linux version 5.3." In the next line I have a button "Update Detected Operating System" My question is Do I need to click the link and update Detected operating system? If I do, is it going to change any configuration on our server?
