Removing Software

A while back, I installed some software using the following: Code:
#wget http://downloads.sourceforge.net/project/wkhtmltopdf/0.12.0/wkhtmltox-linux-amd64_0.12.0-03c001d.tar.xz
#tar -xvJf wkhtmltox-linux-amd64_0.12.0-03c001d.tar.xz -C /opt

I know wish to remove it. Should I just delete it or something else? Thanks

"New Software Can't Be Installed" Ubuntu 14.04

Hi,

This problem seems to have some common solutions, none of which have worked for me so far.

I get this when opening software center in the past few hours:

"New software can't be installed, because there is a problem with the software currently installed. Do you want to repair this problem now?"

Clicking "repair" several times hasn't fixed it, nor have commands like:

Code:
sudo apt-get -f install

and

Code:
sudo apt-get upgrade

Though these have been mentioned elsewhere as solutions for a few people.

My OS otherwise seems to run pretty normally, as far as someone as green as me can tell.

Any fixes for this? I'd hate to format again, especially since my complicated Steam setup takes so long to complete. Thanks!

Lost Software Centre

Recently I installed Ubuntu 14.04.2 LTS Shortly after the 'Software Centre' became corrupted. I made the mistake of deleting it in hopes of being able to restore it. It has been 15 years since I used Red Hat Linux 5, so my Linux for Dummies book doesn't help much. I can study and download .pdf files from the Internet but I want the original back. What command sequence or method can I use to completely restore the 'Software Centre'??

Is LFS The Right Way To Build A Software Update Disk?

I'm very used to working on a linux machine, programing in Unix terminals all through college. That said, I have never needed to work with linux distributions or doing more than some apt-get software installation.

I need to make a CD. I need a machine to be able to boot from this CD. I would like there to be a unix terminal that runs a script automatically. This script must be able to mount an NFS drive, do simple networking (TCP/IP), and update the software on the machine running it through deleting/adding files.

I guess I need an .iso for a linux distro that has files and a script already on it that can be used to update a bunch of these specific machines?

Should I go through the LFS project in order to learn how to do this?

I'm pretty lost and need some help. Thanks!

How To Master Linux? Where Do I Start?

I'm new to Linux, I want to master all of the lovely little details about what makes Linux tick, and how it ticks. I would love to know any suggestions of where I should start. I want to know how anything, the hardware, software, and firmware works. I am wanting to get into computer science, I'm very motivated and am willing to put in the time to learn and master Linux. I figure that Linux is a good of a place to start as any, seeing how there is a lot of source code to study and open source software to play around with.

Is There A Backbox Linux Software Center?

I was told Backbox Linux is a refined Kali linux because there is a full OS behind it. Is there a convenient way to download software for it like a software center? I'm really new to it and wanted to explore.

I Need To Learn How To Install Software On Linux.

Hi. Sorry to be so stupid, but I just managed to load and install this Linux (which I really like a lot) on my previously windows <--(bad) system.
But now I need to upgrade some software (like Adobe flash), and I have no clue how to do this. I understand I should go to my original linux distrubutor, and select software thru them (my "Linux distro").
But actually, it's been awhile since I did the install, and I dont exactly remember where I even got this distribution. (I know, I'm dumb--sorry).
Is there a way I can look at my linux system files and see who my distribution is thru, and where is their website. Or would it be easier if I just went thru the whole download and install of linux again <--(not really looking forward to that).
Or even, am I wrong about going thru the distro to do installs/upgrades?
Anything you can tell me will be greatly appreciated.

How To Open Linux File/software In Windows 8?

Hi,

Could anyone please explain as understandable as possible how could I on my Windows 8 open either single file or install (and use) entire software which is supposted to work on Linux and/or Ubuntu? I have absolutelly NO experience with Linux and have never used it. Honestly, I don't know if there is any difference between Linux and Ubuntu. I want to be inside my Windows 8 while using Linux files/sofware. The only solution I could think of are actually two but neither of them is useful for me:

1. Vmware (i don't know how to use it)
2. Rent remote computer (vps/rdp) with linux OS installed (this would let me be in Windows 8 while being able to use Linux file/software [on remote computer] but sooner or later I would want to have Windows installed there too)

Tried program Linux Reader but didn't work on my Windows 8. Although I would need solution for installation/usage of software (that can be used only on linux/ubuntu), regardless of details***, the current problem is basically related to single files only: I have two files, both in IMG extension. Don't know how to open them because Deamon Tools doesn't handle IMG. The problem is that filesystem in one of them is "Linux" and filesystem in another is "142". The error I am getting when I try to open them is:

"File with harddrive/disc snapshot is corrupted."

But this is most likely because they are supposted to be used in linux environment, hence such question.

*** when i said "details" I was referring to basically anything: type of software, size, purpose, whether or not it needs network connection, whether or not it contains logging in (username password, etc) requirement, etc.

The following solution for current situation (quoted error above) works only partially:

http://www.sysprobs.com/simple-tip-h...thout-software

I am able to open/run/mount IMG if I do what is described on this link (im basically opening iso in this case - see the website) but when opening the virtual drive, the following error message proves that the file can be used in linux/ubuntu only:

"Windows cannot access that drive. Drive could be corrupted. Make sure the drive is in condition that can be recognized by Windows. If drive isn't formatted then format it before usage."

Would need detailed instructions, for total beginner, who has never used linux/ubuntu, what to do in such case: how to use in win8 files/software that are supposted to be used in linux/ubuntu. Also answer on how to open IMG would be highly appreciated.

Kindest regards and thank you a million in advance.

Bzip2: (stdin) Is Not A Bzip2 File. Error

I've been trying to uncompress the file XpressConnect-x86.tar.bz2 using the tar command but I keep getting the following error.

Code:
richard@richard-K52Jr:~/Software$ tar -xvjf XpressConnect-x86.tar.bz2 
bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2
tar: Error is not recoverable: exiting now

I think it may be a problem with the file itself b/c it was provied by our wonderfully incompetent IT dep. I've also tried tar -xvf but that did not work either. I'll attach the file to this post if I can any help would be appreciated.

Getting An Error When Running Make.

Trying to install software/drivers for wireless dongle on my Fedora Linux box. I have downloaded and expanded my files into my /home/me/Downloads.

In my example: /home/cjh/Downloads/LinuxDriver4Fedora_v2.5.0.3
This is where the make file is.

I run make and get an error:
"make -C /lib/modules/3.4.2-1.fc16.i686/build SUBDIRS=/home/cjh/Downloads/LinuxDriver4Fedora_v2.5.0.3/os/linux modules
make: *** /lib/modules/3.4.2-1.fc16.i686/build: No such file or directory. Stop.
make: *** [LINUX] Error 2"

The directory "/home/cjh/Downloads/LinuxDriver4Fedora_v2.5.0.3/os/linux" does exist.

What am I missing? I have run it as myself and root and get the same error.

Any assistance greatly appreciated.

TIA,
