eBay Gallery Plus Option Automatically Checked in Turbo Lister 2

My wife noticed while she was posting items for sell on eBay with Turbo Lister 2 today that the checkbox for adding a Gallery Plus picture was being checked automatically. She didn't want an additional fee for this feature and was annoyed that the box was being checked. She pointed out to me that many other people were complaining of the same problem at Turbo Lister adding Gallery Plus to my Listings! When I checked that webpage, though, I found some people stating that the Gallery Plus images were free when sellers posted items for sale in some categories, e.g., collectibles. Someone posted the following from an eBay announcement in 2009:

We are excited to announce that we are making eBay individual pictures, Picture Pack and Gallery Plus free for items listed in the following categories — Collectibles, Art, Pottery & Glass, and Antiques. We are committed to the success of our sellers and to continually improving the overall experience for all of our customers — both buyers and sellers

When I checked an eBay "help" page on Gallery Plus, I found no mention of the above statement, but I did find that information on the link from that page to an eBay fees information page.

When I checked the auction items in Turbo Lister 2 for which she was seeing the box being checked even when she had unchecked it, I found she had designated the category for them items as "collectibles", so I told her she shouldn't see any Gallery Plus fee for those items.

Installing Google Chromium on CentOS

Google Chrome
Logo If you have a Fedora 12 or Red Hat 6 (RHEL) or later versions of Linux on a system and would like to install the Google Chrome browser using the YUM package manager, you can do so using the following steps.

Note: You can determine which version of those operating systems or CentOS you are using by examining the contents of /etc/redhat-release.

  1. Add Google's own YUM repository to be sure you obtain the latest version of the chrome browser, which will allow you to easily ensure you can keep it up-to-date. To do so, create the file /etc/yum.repos.d/google.repo and place the following lines in it depending on whether you are using a 32-bit version of Linux or a 64-bit version. You can check whether you have a 64-bit version by issuing the command uname -a. For a 64-bit version, you will see x86_64 in the output.

    32-bit

    [google]
    name=Google - i386
    baseurl=http://dl.google.com/linux/rpm/stable/i386
    enabled=1
    gpgcheck=1
    gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub

    64-bit

    [google64] name=Google - x86_64 baseurl=http://dl.google.com/linux/rpm/stable/x86_64 enabled=1 gpgcheck=1 gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub

    Note: you could also put both the 32-bit and 64-bit repo information in the same file, if you wish.

  2. Install either the stable, beta, or unstable versions of Chrome from the root account. I would recommend using the stable version.

    ## Install Google Chrome Stable version
    yum install google-chrome-stable

    ## OR install Google Chrome Beta version##
    yum install google-chrome-beta

    ## OR install Google Chrome Unstable version##
    yum install google-chrome-unstable

However, if you are using CentOS 5, you won't be able to install the Chrome browser using the above steps. When I attempted to install the package on a CentOS 5.5 system, I saw a message indicating that version 3.2 of the lsb package was needed:

Missing Dependency: lsb >= 3.2 is needed by package google-chrome-stable-6.0.472.53-57914.x86_64 (google64)

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

When I tried updating the lsb package, I saw the following:

# yum install lsb
Loaded plugins: fastestmirror, priorities

Nothing to do

I had similar results when I changed the contents of google.repo to try the 32-bit version, instead.

I found lots of other people reporting the same problem with earlier versions of Red Hat Enterprise Linux (RHEL) 5 and versions of Fedora prior to 12. E.g., there are similar reports at How to install google Chrome in RHEL 5. and Add support for RHEL/CentOS for OS compatibility. At the latter problem report webpage, I found a suggestion from andrewrjones that people wanting to use chrome on CentOS check Chris Staite's webpage, Chrome on CentOS where he provides Chromium for CentOS. Chromium is Google's open source alternative to their Chrome browser.

You can download Chromium for CentOS 5 from his website or from this website. Chromium is an open-source browser project behind the Google Chrome browser that aims to build a safer, faster, and more stable way for all users to experience the web.

Download Chromium
Chris Staite
MoonPoint Support

Once you've downloaded it, you will need to unzip it and untar it. When you extract the contents of the tar file, a chrome directory will be created beneath the current directory. Make that the working directory and run chrome-wrapper.


# gunzip chrome.tar.gz
# tar -xvf chrome.tar
# cd chrome
# ./chrome-wrapper

You will then be asked to choose the search engine you wish to use from Google, Yahoo!, or Bing.

Chromium - Choose Browser

Once you've started Chromium, you can control and customize it, by clicking on the wrench symbol in the upper, right-hand corner of the Chromium window.

Chromium - Start

When I ran chrome-wrapper, I received the error message below, but the program ran.

# ./chrome-wrapper
[5578:5592:5060312371904:ERROR:base/nss_util.cc(184)] Error initializing NSS with a persistent database (sql:/root/.pki/nssdb): NSS error code -8174

The program that Chris provides is a 32-bit one.

# file chrome chrome: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), not stripped

I found a discussion of the problems with Chrome and Chromium as well on CentOS systems at Google chrome for CentOS ?? that indicates Google has no interest in supporting Chrome on CentOS 5. There's also helpful information there on the Chromium software available from Chris Staite's site and how to resolve problems encountered with it on CentOS systems, but, since I have a lot of more pressing things to get done, I decided I couldn't afford to spend any more time troubleshooting issues with Chrome and Chromium on CentOS and just deleted the Chromium software from the system on which I had placed it.
