"New Software Can't Be Installed" Ubuntu 14.04

System Info:

I have normal user in CentOS 7 whose name is "mostafa" (the name of the account).

I naturally have another user called root with all privileges. User "mostafa" is put into sudoers file, too.

The OS is installed in VmWare, so the system is all mine.

Problem:

Now I create a file with touch file.sh and put a command in it, but when I want to run it with Code:

sudo ./file.sh

, an error is shown that the command Code:

./file.sh

does not exist. But if I Code:

 sudo chmod 777 ./file.sh

then it gets run. My question is that, why should I use Code:

chmod 777

when I myself have created the file, and I am in sudoers.

Can anyone explain me why shuold I still use Code:

sudo chmod 777

when the creator of the file is me.

I don't know why I want this, but is there a way the Code:

sudo aptitude install <package>

or Code:

sudo aptitude upgrade

command could bypass the confirmation stage? It's always occurred to me shouldn't there be some command parameter for install/upgrade that does the work?

Let me give an example. Suppose I want to install Variety, the wallpaper changing application. Now, I know that I want to install the software with all the dependencies it requires to install/run - the entire package. So, isn't it obvious that I would press Y when aptitude shows the info what it's going to download/install and asks for permission?

I can't, however, imagine scenarios when seeing that information I'd change my mind and press N to abort the install/upgrade procedure.

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:

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.

Hi all,
i am new to linux, i am using Centos 6. There is some problem in the network settings as i am able to browse internet from a browser but when i am trying to use the terminal (using ping command) for any of the website (say www.google.com) nothing is happening. suppose i want to install some software (like hdf5), when i am using "sudo yum install hdf5" it shows large number of error massages like "error could not connect to the host". It would be a great help if someone provide the solution.
Thanks in advance.

Hello, y'all with vast Linux knowledge, I've built my own gaming desktop, here are the specs:
1-MOBO Asus M5A78L-M LX Plus
2-AMD Radeon Graphics R9 270, 2GB DDR5 Memory
3-2 Hyper X Memory Cards totalling 16 Gb of RAM

Have installed and runninbg Zorin 9.0 Ultimate (Ubuntu 14.4) - MY PROBLEM, I am unable to downlolad any games especially "Minecraft", "League of Legends" and a host of other games on "Steam". I have Wine Geko (32 bit) 2.1 version installed and have Winetricks as well, when I open it I can install a host of games, however, nothing is installed. This is the last straw for me, I have no clue what to do do being a Newbie and unfortunately the folks at "Zoringroup/helpdesk" have been absolutely useless as well. Thanks.

Running mint 17.1 (64 bit) Cinnamon

I've spent a bunch of time trying to troubleshoot my setup of my ftp. Currently trying to get it to work using the virtual users option. I am following this guide http://ubuntuforums.org/showthread.php?t=518293. I've hit a snag that I can't seem to get around. The libdb3-util is where I'm having trouble. When I input the code "sudo apt-get install libdb3-util" my results are as follows:

Code:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libdb3-util

I have searched around a little, found someone else that had a similar problem, and was able to use db4.7-util to correct their problem. However, when I attempted this, it was unsuccessful. Is there a newer libdb/db I should be installing? If so, when I install it will it alter any of the code I've used from the guide?

I've been following the guide verbatum from the start of "Virtual users with TLS/SSL/FTPS and a common upload directory - Complicated vsftpd" and have stalled at the point of installing the libdb3-util.

Hi, I've just recently installed MySQL connector/c from source code on my Slackware 14.1 x64

I read the official instructions of the connector but I felt a bit disorientated when I read:
Code:

1 -Change location to the top-level directory of the source distribution.

I interpreted that I have to go to the "highest" directory Code:

/

So I wrote: Code:

 
        #                            cd /

root@- /#                            tar xzvf /home/normal/Downloads/mysql-connector-c-6.1.6-src.tar.gz 

root@- /#                            cd /mysql-connector-c-6.1.6-src/

root@- /mysql-connector-c-6.1.6-src# cmake -G "Unix Makefiles"

root@- /mysql-connector-c-6.1.6-src# make 

root@- /mysql-connector-c-6.1.6-src# make install

Then I did:
Code:

ln -s /usr/local/mysql-5.6.25/include /usr/include

But when I try to compile a program in c with #include <mysql.h> i get this error:
Code:

# gcc ctemp.c 
In file included from ctemp.c:2:0:
/usr/include/mysql.h:57:27: fatal error: mysql_version.h: No such file or directory
 #include "mysql_version.h"
                           ^

What can I do? Thanks a lot and sorry for poor english

PD: If you need the official instructions I paste here the link: https://dev.mysql.com/doc/connector-...on-source.html

I have the below URL

http://linoxide.com/ubuntu-how-to/awstats/

in this URL , it have the command "sudo a2enmod cgi" to check the cgi is installed or not , but when I run it , it pops "bash: a2enmod: command not found" , I tried to install it by yum install a2enmod" , but got the below message , would advise how to install it .
Code:

Loaded plugins: fastestmirror

I rescently installed Ubuntu 14.10 (AMD64) on my ASUS X53U (CPU: Brazos Dual Core E350 1.6 GHz GPU: HD 6310M, 3GB RAM) I downloaded Steam from the website, installed it, got some errors and managed to ruin everything (low res, really slughish) by just pasting commands into the terminal that seemed to make sense while I actaully had no idea what I was doing.
So I "threw everything out the window" and installed the OS fresh again.
Everything is fresh. All I have done is run the software updater and installed Grub Customizer so I can access Windows 7. (don't even have Steam installed)
So what are the exact steps on setting up all the OpenGL stuff and getting TF2 to run? (simply things to paste in the terminal would be best)
The most helpful person gets a game of their choice on Steam for under 10 euros.
I know that it should be possible to find everything myself but I just don't have the time or intelligence for that. That's why I would rather just have someone else spend time helping me and buy them a game for their efforts.

Code:

alice@alice:~$ grep 1003 /etc/group
alice:x:1003:
alice@alice:~$ grep 1003 /etc/passwd
alice:x:1003:1003:Alice,,,:/home/alice:/bin/bash

So there's nobody in alice's group except alice (for whatever that's worth)

Code:

alice@alice:~$ ls -ld dollstuff
drwxrwxr-x 2 alice alice 4096 Jan 28 10:55 dollstuff

alice clearly owns and has full access to the directory "dollstuff" which resides in her home directory

Code:

alice@alice:~$ grep 1005 /etc/group
common:x:1005:alice,dilbert,wally

there's another group of which alice is a member, and alice wants to share her directory with the other members of the group

Code:

alice@alice:~$ chgrp common dollstuff
chgrp: changing group of ‘dollstuff’: Operation not permitted

Why not? dilbert and wally do this very same thing on their machines on a regular basis. All are running fully updated Ubuntu 14.04.

"chown ladybug:common dollstuff" is also disallowed, although "rm -r dollstuff" does work.
