I have currently installed a version of rpm (x.rpm) that needs to be renamed in the next version (y.rpm). To accomplish this, I decided to obsolete the old (x.rpm) rpm. When I run the rpm –Uvh y.rpm on the new rpm here are the steps that takes place:
-Pre-transaction
-Pre-install
-Post install
-Pre uninstall
-Post uninstall
However, my post-uninstall script has some clean up steps that goes and does an rm –rf for some folders. The post-uninstall for both version of the rpm is exactly the same so now, when I installed the new rpm (y.rpm), some folders that were required by the new version gets removed because of the post-uninstall script.
How do I get around this issue?
Any help is greatly appreciated.
Thank you.
Here is what i would do:
create a newer version of x.rpm with changed post uninstall script that doesn't remove folders
update x.rpm on all machines
wait for a while (depending if this is an in-house project or an open project on the internet)
start deploying y.rpm

I'm trying to uninstall the current version of Eclipse IDE in my RHEL machine by simply deleting all the files like:
sudo rm -rf ~/.eclipse
sudo rm -rf ~/eclipse-workspace
I also tried
sudo yum remove 'eclipse*'
However, these didn't seem to solve the purpose.
Any help will be appreciated, thanks!
Applications on Linux systems are most often installed using so-called packages, which are managed by a package management system. In the case of RHEL, packages use the RPM format, and the package manager of choice is a tool called yum.
Both installation and removal of software (packages) should be done using yum, so as to allow the package management system keep track of all installed files and current status. Therefore, you shouldn't try to remove software by simply deleting files from the file system. Instead, use the yum command. See the RHEL System Admin Guide for a detailed explanation of how to use yum to search, install, upgrade, and remove packages: Working with Packages.
You have tried the correct command (yum remove <package-name>), but you need to use the correct package name. On RHEL 7.4, the latest version of Eclipse is available as a part of the DevTools channel, and the package name is rh-eclipse47 (see Enabling the Red Hat Developer Tools Repositories). Note that you may have also installed an older version, which would be, for example, rh-eclipse46.
To find out what is the name of the package you have installed, you can run, for example, the following command:
yum list installed | grep eclipse
There is also the possibility that you installed the software not from an RPM package but manually, e.g. from a .tar.gz file distrubuted from eclipse.org. If that's the case, you will need to use the uninstaller program supplied with that distribution of the software.
Write command as:
rpm -qa|grep eclipse
This will give a list of installed packages. Remove all the packages by giving below command:
rpm -e *package-name*
Done!!!
I am looking for the latest versions of skulpt.min.js and skulpt-stdlib.js for my website. I am new to GitHub, and asked them. They said to make a new release. So I did. And I can't find the files I am looking for. Where could I find the latest releases?
The latest version of skulpt.js and skulpt-stdlib.js are now provided through bower, which is a package manager that keeps track of your packages and makes sure they're up to date.
Bower can be installed with npm running the command
npm install -g bower
From there you can get skult.js by running this command
bower install skulpt
If you don't want to use Bower, you can download it from here
Or you can get it as .zip or .tar.gz
Here: https://github.com/skulpt/skulpt/releases/tag/0.10.0
Look in the Downloads section. Here's the link: https://github.com/skulpt/skulpt/archive/0.10.0.zip
Note you'll have to build the project to get the .js files. See this https://github.com/skulpt/skulpt#building-skulpt for details.
I'm unfortunately not very experienced in CentOS administration, and was hoping someone might be able to help me understand and get past a small hurdle. I was hoping to run yum update on the system, but ran into some Transaction Check Errors:

It sort of looks like it's saying that some newer version files are conflicting with older version files. Is there a standard way to fix this? I was mainly just trying to update so that I could install Java later, but wasn't expecting to run into these errors. If it helps, the server is mainly being used for hosting a few websites with apache and mysql. Thanks so much for any help, it's greatly appreciated.
Edit: To add some more clarification, I had previously edited the baseurl variable in the /etc/yum.repos.d/centalt.repo file, which was originally set to
baseurl=centos.alt.ru/repository/centos/6/$basearch
The reason I changed the location was because I was previously getting an error when trying to run yum update, mentioned in this other stackoverflow question https://unix.stackexchange.com/questions/132674/repository-metadata-repomd-xml-for-repository-mratwork-centalt which had an answer recommending replacing the URL with
baseurl=mirror.sysadminguide.net/centalt/repository/centos/6/$basearch
Is there a different url I should be using instead?
You have a non-official repository which provides the php55-* packages which conflict with the official php-* packages.
You currently have the php-* versions installed.
If you want to switch you can try manually installing the matching php55-* package for every php-* package you have installed in one yum command (though that may not work).
If it doesn't, you might need to remove all the php packages you have installed first and then install the php55 versions after that.
I have an install.ps1 script in my NuGet package. This script runs both during a new install (after all the files have been copied) and during an upgrade.
I want to show a Getting Started page during a new install, but for an upgrade I want to show the Release Notes.
I found this great answer that tells how to open a URL and it works great. But I am stumped on trying to tell the difference between a new install and an upgrade.
The best solution I have come up with so far is to add a Release Notes link to the top of the Getting Started page, but that is something that could easily be missed by upgraders, and is an unwanted distraction for new installers.
I don't think it's possible to know if the current operation is install or upgrade. When NuGet upgrades a package, what NuGet does is basically uninstall the existing package and install the new package.
I suppose you could do something with install.ps1 that "dirties" the project in some way on the first install, which you will not clean up with uninstall.ps1. Maybe insert a dummy file into the project (outside of the normal NuGet handling, so the file won't get uninstalled automatically) or add some other dummy element to the project file. Then, when you see those "leftovers" from a previous install (which were purposely not cleanly uninstalled), you will know that you are installing an upgrade.
I am using Ubuntu 12.04. I have installed doxygen 1.8.3.1 using make install.
I would like to uninstall the doxygen built by make, but I don't find any way to do it using make (uninstall or clean...).
In the Makefile there is no reference to uninstall it the software. :(
Unfortunately I can't use the sudo apt-get remove doxygen because it wasn't an installed. :(
I don't find anything related on the internet.
Can anyone help me, please?
Thank you in advance,
Fabiola
There is no "uninstall" target. You need to do a "rm" be hand. If you used the standard prefix path "/usr/local" then
rm /usr/local/bin/doxygen
rm /usr/local/man/man.1/doxygen.1
(more if you install the docs are wizard). Depend on the user used for install, you need sudo to do it.
I know this question is old, but since it is the first result in google I would like to share another way of uninstalling Doxygen built from source. In the build directory where you've ran make there should by a file name install_manifest.txt. That file contains paths to files that were installed using make install command. All you need to do is to run the following command:
sudo xargs rm < install_manifest.txt
Of course this assumes that you've kept the build directory or at least the install_manifest.txt file. If not you need to remove the files by hand as somebody already suggested.
