True. I just hope that the various alternatives will pool their resources. 
History has shown that RHEL derivatives require a lot of effort to maintain. It 
would be a shame to dissipate that effort among a number of competing distros.

There are some workarounds. You could install thunderbird 68.8.0
directly from thunderbird.net, or get a better integrated installation
from flathub.org. You could log into your CentOS 6 box from CentOS 8 and
run thunderbird 68.8.0 remotely. No doubt there are others.

I recommend installing zoom from flatpak:

It will pull in the freedesktop runtime, which contains the required
libraries. No need to fiddle with LD_PRELOAD and the like.

I use the tarball provided by upstream on CentOS 7, since the
distro-provided version is quite old. I created a 'tomcat' system user
and gave it ownership of the extracted files under /opt. I also wrote a
simple systemd unit file to manage the service in the usual way.

If you take that approach be sure to subscribe to the tomcat-announce
list in order to receive update announcements.

I'm not aware of a way to group windows when running GNOME in classic
mode, which is the default in CentOS 7. However, if you use GNOME in
standard mode with the 'Window list' extension enabled, you can
configure that extension to group windows.

You could also enable the 'Application list' and 'Places status
indicator' extensions in standard mode to make the environment more
familiar.

CentOS 8 runs GNOME on Wayland by default. X forwarding cannot work in
those circumstances. To change that, choose "GNOME on Xorg" after
clicking on the gear icon on the login screen.

I recommend running ssh with the -X or -Y flags when connecting to the
remote box. It's more secure than using 'xhost +'.

Another reason to favour the flatpak repo. Upgrades are pushed by the

I've been running Debian stable on various machines over the course of
about 17 years. I have *never* had to reinstall.

That may be, but in view of the fact that you can even get a version of CDE

distribution like Centos.



I'm not suggesting that it will. A few years ago, soon after the source

CentOS 6 VM. Why? Because I could. But would I conduct any serious
business in that environment? Of course not. And why is that? Because it
receives no enterprise support.

It could well be that someone is organising it. On the other hand, it
could be not. Either way, it will not be supported by RHEL and CentOS.

Nope.

OTOH, if I was forced to use Gnome, I may well go shoot myself.

It's unlikely that the Skype developers have done much testing on CentOS
7 specifically. You might have better luck with the flathub version[1]
which uses a common runtime across all distros.

I see you're using network-manager. Does the file
/var/lib/NetworkManager/dhclient-.conf contain a line
beginning with 'send host-name'?

Also, please stop network-manager and issue the command I gave you

This is a known issue, and was mentioned on this list recently. The
problem is that Mate in EPEL needs to be updated to work with CentOS
7.6. Perhaps keep an eye on changes to the EPEL repo before attempting
the upgrade again.

Both GNOME and KDE Plasma offer you a menu of applications by category,

No. The updates provided over an x.y series are relatively minor and
generally well tested. It's very different to the version churn
associated with Fedora. The updates also include important security
fixes, and it's not advisable to try to apply those in isolation. But I
would add the usual caveat: if you're doing anything business-critical
with your installation, test the upgrade on comparable hardware first.

Being from the EPEL repository, dnf is not supported by CentOS. So I
would avoid using it on a machine which serves a critical function.

Again, EL Repo packages are not supported by CentOS. Therefore the above
warnings apply here too.

If, on the other hand, you can afford to tinker with the system and
experiment a bit, then go for it. Oh, and welcome to the CentOS
community.

I think it goes a bit deeper than a missing provides (in the packaging
sense). Only samba3 contains libwbclient.so.0:

$ yum resolvedep libwbclient.so.0
0:samba-winbind-clients-3.6.23-46el6_9.i686

That can be verified using repoquery (from the package yum-utils):

$ repoquery -l samba4-winbind-clients.x86_64 | grep wbclient
(no output)

The error messages above tell you what the problem is: there is a
conflict between the installed samba4 packages and the samba3 packages
you are trying to install. It looks like someone uninstalled various
samba3 packages using rpm (instead of yum), probably in order to install
samba4, but breaking dependencies of other packages in the process.

I've seen that message, on and off, as well. Like you, I have no idea

Have you been able to connect the appearance of the message with any

When you open the Xfce display settings[1], is a resolution higher than

What happens when you start virt-manager from a terminal emulator? Do
you see any output?

Is libvirtd running? The command 'systemctl status libvirtd.service'
will tell you.

Yes, but virt-manager will require various GTK and GNOME libraries

Mate in epel still uses gtk2, whereas the applications you mention use
gtk3. So I'd say you need to choose a theme with support for both.
Adwaita is a good choice in that regard.

No such problems here.

I suggest you try testing firefox with any plugins and extensions
disabled. Failing that, try "refreshing" firefox[1].

Have you installed any packages from non-standard repos? I've had some
problems in the past with ffmpeg from the nux repo following a firefox
upgrade (problems which were promptly fixed by the maintainer of that
repo.)

All you need to do is change the value of the dconf key
/org/gnome/shell/enabled-extensions. Using dbus to do that is overkill.
I suggest you use gnome-tweak tool (as I suggested earlier) or, if you
require scriptability, the dconf or gsettings commands.

Those commands are for the GNOME 2 (and possibly MATE) desktop
environments. In GNOME 3 you use gnome-tweak-tool to disable the "Window
list" extension. Assuming you are running GNOME 3, of course.

The package puts some files in /etc/xdg/autostart/. You could edit those
to prevent autostart.[1]

Another option is to place the file .config/gnome-initial-setup-done in
the user's home directory, containing the text "yes".

You can set the variable in the cron job itself. See, for example,
/etc/cron.d/0hourly, where several variables are set.

You can install and run 32-bit Skype on 64-bit CentOS 6. I recommended
the Nux repo[1] for convenience. The various 32-bit dependencies will be

Be aware that the file
/usr/share/polkit-1/actions/org.freedesktop.login1.policy is not a
configfile and will be silently overwritten when systemd is upgraded.

In earlier releases of PolicyLit local changes were made in
/etc/polkit-1/localauthority, but I don't know if that approach still
works.

You can use GNOME Disk Utility (package gnome-disk-utility) within a

What happens when you issue the command 'ssh -p  localhost' on the
host? I'm assuming that an ssh server is running on the guest and that
there are no firewalls getting in the way.

VirtualBox gives you a GUI for setting up port forwarding from the host
to the guest. It's under Machine -> Settings -> Network -> Advanced. Did

You will always find examples of release upgrades going wrong. The
Debian release notes[1] are very clear about the pitfalls of performing
out such upgrades remotely in particular. My own experience has been
more fortunate, as I have carried out multiple release upgrades over the
years on many different machines. But I wouldn't dream of attempting
the equivalent on a CentOS installation.

In the case of RHEL 5 and 6 the former way is recommended[1]. I don't

I recommend the package-cleanup command from the yum-utils package. See
the '--oldkernels' option in particular; it will remove obsolete
kernels, i.e., those which are no longer installable from your yum
repositories.

The package description (yum info xrdp): "The goal of this project is to
provide a fully functional Linux terminal server, capable of accepting
connections from rdesktop and Microsoft's own terminal server / remote
desktop clients." If you connect to the server(s) using Windows clients,
then it's likely that you need this package.

I notice that xrdp is in the EPEL repository rather than the standard
CentOS repositories. That might explain why it is not installed via
kickstart.

Others have complained that this is not the place for an extended
discussion on Debian, so I'll just direct you here:

https://wiki.debian.org/LTS/

If you have any questions, I suggest you post them to debian-user. I am
subscribed to that list, and will be happy to resume the conversation
there.

You are describing Debian sid/unstable, which is contunuously updated,
and where there are no releases in the usual sense of the word. Debian
stable releases are a different matter, and correspond very closely to
major releases of RHEL/CentOS. There is always an upgrade path between
consecutive releases of Debian stable.

It will help if ffmpeg is installed. But ffmpeg is not in the official
repository, so it will not be installed unless you went of your way to
get it.

What you can try is to refresh your FF profile[1]. I found that FF 45
was crashing on gmail (so no video involved) until I did that.

No, flash is still supported by Adobe on linux. Only security updates,

I agree with that sentiment. Sometimes, however, there are circumstances

In case anyone else has this problem, the issue seems to be that firefox
retains stale information about the plugin status. You can force a
refresh as follows:

1. Exit firefox
2. Uninstall flash-plugin
3. Start firefox, and exit again
4. Install flash-plugin

You should receive an email confirmation from Red Hat. In my case it
only arrived after I had entered my RH account details when installing
the new OS. That could just be a coincidence, of course.

Updates are available through yum in the normal way. Dnf is available in

One thing that struck me is that the (free) developer subscription is
valid for only one year. It is not clear whether the subscription can be
freely renewed thereafter. I wouldn't advocate a full migration just
yet!

No, many before you have similarly bemoaned the changes made during the
transition from GNOME 2 to 3. I suggest you take a look around the
extensions website[1] for extensions which restore the missing
functionality. Use gnome-tweak-tool to install and remove extensions.
They can be a bit hit-and-miss when it comes to compatibility with the
particular version of gnome-shell you are running.

Since gnome-panel and 'flashback' mode have been removed from GNOME 3,
gnome-applets is no longer required or available. Much of the
functionality of traditional applets is available by means of extensions
to gnome-shell. See the various gnome-shell-extension-* packages.

I think the OP is talking about the file type that Nautilus reports when
you right-click on a file and bring up the 'Properties' dialog.

In my case (also CentOS 6) Naulitus reports 'Genesis ROM' for files with
the .md extension. The file command, on the other hand, reports 'ASCII
English text'.

The file responsible for the behaviour of Nautilus is
/usr/share/mime/application/x-genesis-rom.xml, which appears to have
been generated by update-mime-database.

Run 'gnome-session-properties', go to the 'Options' tab, and check
'Automatically remember ...'.

I don't use that setting, and I have no idea whether all applications
honour it. But it's worth a try.

That article seems unnecessarily complicated, at least as far as CentOS

 it basically comes down to this.

 I use an apache interface to my application, the URL line has

 I have a crude encoding (wouldnt even call it encryption) that I use

 I'd like to make that more robust. I started looking and found mcrypt
 (which I mentioned in the first post)

 But that did not compile from source, and is not available in the
 standard yum install. Other repos have it but that

 may not be an option for me due to other reasons No problem.


 So I started thinking about does GPG support something similiar like
 mcrypt? Easy way to encrypt a line for URL.

 That is where my goal lies... Way to encrypt a URL string with what is
 standard in CentOS 6.

Can you not just use HTTPS instead of HTTP? Also, it is preferable to
send data in an HTTP(S) POST rather than as query parameters to a GET.

 The -Y change was introduced in Fedora Core 3, in November 2004.  The

 At this point, I don't think it's even possible to set

The perceived difference was a general impression on my part, and not
