How to upgrade Citadel on Ubuntu Server Edition 12.04 LTS?
location: ubuntuforums.com - date: July 18, 2013
I have a Ubuntu 12.04 Server Edition in production with Citadel as mail server. It runs well with heavy traffic so I am afraid to mess with it. However, there's an annoying bug in the Citadel version that comes on 12.04: The "Delete" button in web mail doesn't delete messages but only hides them until you refresh. On the Citadel version coming with 13.04 this is fixed. I would really like to be able to upgrade Citadel, but when I try I run into dependency problems and it won't install. I was wondering if anyone here could help me find a way to get a newer version of Citadel installed on 12.04 that doesn't include building it on the server something I would rather not do on this particular system.
Ubuntu Server, Precise 12.04 How to admin? I am very confused.

I humbly ask you to post only if you know exactly what is about and you have experienced on your own skin. (Example: I have received some advices in the past regarding boot-splash manager which broken the system up. They where good but maybe for another ubuntu version)
This is what I did in general

I am working with my tiny box with ssh (I have changed the port to another number like 61980), and putty but I have also installed grafical interface.

Now the problem is that is using more ram ~203 mb, and I

We are migrating to Ubuntu Server Edition from CentOS. We use the Citadel mail/groupware server a lot but there's a bug in Citadel resulting in the delete button in web mail not to work. The bug is described here:
Is there a way to fix this without upgrading either Ubuntu Server or Citadel Server, and what would it take to run a newer version of Citadel Server on 12.04 to fix this problem?

Install Ubuntu Enterprise Cloud (12.04)
location: ubuntuforums.com - date: May 31, 2012
I am installing Ubuntu Enterprise Cloud using the image of Ubuntu Server 12.04 for cloud, however, the installation result is not the expected.
During the installation, no screen (not even one) regarding cloud options appears. I was expecting for the screen where I was to select cloud installation mode (Cloud controller, Walrus storage service, etc), or the screen to configure the cluster name, but no one of this interface/menu appeared.
It is like if I choose the option "Install Ubuntu Server" instead of the option "Install Ubuntu Enterprise Cloud" from the main menu of the Ubuntu installation CD.
Anyone can help me about this problem?
Ubuntu Server LTS 12.04 Adding SSL to webserver causes hang on boot?
location: ubuntuforums.com - date: June 28, 2013
Added SSL to a webserver only to find that when the prompt comes up to enter the password, no time is offered to actually type it in. Apparently additional processes take over with the new default concurrent bootup. The system later hangs. I CAN boot using the recovery mode + resume normal bootup, as this gives me the time to enter the passphrase. Editing the startup in /etc/init.d/rc by changing concurrency to "none" didn't help.
MySQL uses CPU 161% @ Ubuntu Linux Server 12.04.1
location: ubuntuforums.com - date: April 11, 2013
when i check the running-processes I notice:
CPU load averages: 8.76 (1 mins) , 10.82 (5 mins) , 11.32 (15 mins)
CPU type: Intel(R) Xeon(TM) CPU 3.00GHz , 2 cores
ID Owner CPU Command
943 mysql 161 % /usr/sbin/mysqld
When I check the memory use:
Real memory: 3.45 GB total / 2.70 GB free Swap space: 4 GB total / 4 GB free
ID Owner Size Command
943 mysql 383568 kB /usr/sbin/mysqld
For some reason the MySQL-program uses a lot of CPU. It uses about 161% of CPU.
Is there a way that i can modify MySQL to reduce the CPU-use?
using Ubuntu Live CD 12.04 to purge virus on Windows Vista
location: ubuntuforums.com - date: December 3, 2013
A friend who is not too computer savvy has telephoned me for some technical help.
She has a virus contaminated Windows PC and is now being blackmailed by a caller to remove a planted virus.
I've told her to not use her PC until I have a look.
From what I gather I believe the attacker has been given remote access to her PC since she
followed some telephoned instructions from this rogue caller.
She is seeing a white screen.
I've warned against crook callers who masquerade as Microsoft Support and plant viruses.
Another possibility is her younger family using the shared PC for games.
Tomorrow I'm going to pay a visit with my Ubuntu 12.04 Live CD to try to sort this out on the Windows box.
What procedure is recommended to run Ubuntu live CD to clear out host PC windows virus(es)?
I've looked at Clamtk but the latest Clamtk runs on 13.04 (not my 12.04).
Could I run AVG (windows only) in wine on Ubuntu 12.04 to clear out viruses on the (contaminated) Windows partition?

Software Center (Lubuntu/Ubuntu/Linux Mint) 12.04 LTS
location: ubuntuforums.com - date: November 8, 2013
Since all systems are based on Ubuntu 12.04 LTS. Do all software centers contain the same programs? Or one has more options than the others?
I know who you can install Ubuntu software center on Lubuntu and Mint. But wonder why. Only explanations is if there is a difference somewhere. But even then, if you find it to install, it will also install all required packages.
Anyhow, a bit confused...
Semi mechanical keyboard gaming failed to work on Ubuntu 13.10, 12.04
location: ubuntuforums.com - date: December 11, 2013
Recently I have bought a new semi machanical keyboard to couple with Ubuntu and Windows 7 64bit (usb keyboard). The keyboard is currently working very well on Windows 7, but generally failed to work properly on Ubuntu 13.10 and 12.04, I have tested all recent versions of Ubuntu. Crunchbang 11 also failed to work too (and maybe I'll try to checkout Arch or Fedora later).
As I have checked carefully and in detail, when using showkey command to check which key invokes, the result is that Ctrl/Alt/Win keys invoke Shift keycode. And the backlight of capslock, numlock and scroll-lock didn't toggle on, but their functions are fine. The main problem is Ctrl/Alt/Win keys, I guess there're reason to this kind of matter, maybe the "rollover" or "ghost typing" feature in gaming keyboard confused the kernel/keyboard driver.
I don't know whether a way to fix this problem, by mapping to other keys or somehow, but I hope there will be a way to deal with keyboard driver.
