How The System Upgrading Works On Linux Distributions

Okay so I am having major issues getting python to work on Ubuntu 12.04 and other programs I want to run exclusively on this system. Just so you all know - I do not understand computer lingo much so I have a million definitions and how to's . I've kind of been thrown in the deep end on something and the I.T. guru (sorry for the frustration - but effectively this boso worked for MY company) belittled me basically calling me stupid & incapable of being able to configure a basic desktop system.

Anyways my ex from years ago also worked in I.T and played with different operating systems at 1 point so I had used Linux before and remembered it was geared to what I needed. I have installed 12.04 (trialled the latest 14 version as well but opted for the older one for more guidance. So I have everything I need for what I am doing except for 1 minor detail. I am so confused on entering the command lines

can anyone guide me to where there's a really simple straight forward guide to getting 2 programs to run and python to work? I know it's just entering command prompts so to speak but I can't get them to work or know the file directories for the locations of the programs.

ANY HELP WOULD BE APPRECIATED!!!!!!

What are the recommended best security practices for using Firefox on a new Linux system (Centos 7 in my case)? I only access the web using Firefox using my regular, non-root, account. Other than that, what Firefox and/or system settings should I enable/disable in order to safeguard my system from malware scripts, viruses, etc? Also, are there similar Thunderbird settings that should be enabled/disabled?

Thanks in advance from a new Linux user

New to Linux. Run with either Ubuntu Linux on USB or installed on Aspire laptop.
Problem: Chromium and Eclipse act like they are starting but no window opens.

For Eclipse, icon comes up, workplace prompt answered, icon reappears and counts down but no window comes up.
pstree shows that both Chromium and Eclipse have threads running.
Booting with same USB to different computer and all works fine.
Have used both 32 bit and 64 bit USB boot on 64 bit Aspire with no success.

Firefox comes up and works fine

I am using the ubuntu studio Distro and one of the pro music programs is called ardour. When the program is loaded there is no way to get access to the other programs. The dock doesn't function and the ubuntu sign has disappeared. I can't even log off or see my name in the top right hand of the screen. My only option is to quit the program. There aren't any workspaces visible and no matter where I put the mouse clicker nothing appears. What am I doing wrong? I'm sure it's not just ardour that does this.

Hi all ,
i tried to update firefox 24 to firefox 35. Found a tutorial how to install it and did
#chown -R root:root /tmp/firefox && mv /tmp/firefox /opt/firefox-latest
#ln -s /opt/firefox-latest/firefox /usr/local/bin/firefox-latest
and now run it with firefox-latest.
I had actually the both versions of firefox and with pkgtool tried to remove firefox 35 but it cant, so i uninstalled firefox 24. Now i have troubles with flashplayer. how can remove firefox 35 ?

In August of this year I'm going to build a dedicated linux audio computer. I have been using ubuntu studio on my cheapo dell optiplex to learn linux and to get used to different programs and see which ones I need.

Lubuntu seems to use less cpu than ubuntu studio for the same program. I don't want any other programs on my system part from ardour, jack and a few misc MP3 players. All audio. It says that ubuntu studio is a low latency program, does this mean that Lubuntu isn't low latency? It seems that Lubuntu is running the program easier but I'm nervous to go with it because I fear it may be missing certain components to keep it less needy of cpu power.
What are your thoughts on this.

hi all

I am learning systemd and how to add new services as part of the LFS201 course and I have a question about the services:
Code:

Lab 4.2: Adding a New Startup Service with systemd
For example a very minimal file named
/etc/systemd/system/fake2.service:
[Unit]
Description=fake2
After=network.target
[Service]
ExecStart=/bin/echo I am starting the fake2 service
ExecStop=/bin/echo I am stopping the fake2 service
[Install]
WantedBy=multi-user.target

Code:

root@ubuntu:/etc/systemd/system# systemctl start fake.service
root@ubuntu:/etc/systemd/system# systemctl status fake.service
 fake.service - fake
   Loaded: loaded (/etc/systemd/system/fake.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

May 16 11:41:05 ubuntu systemd[1]: Started fake.
May 16 11:41:05 ubuntu systemd[1]: Starting fake...
May 16 11:41:05 ubuntu echo[1798]: I am starting the fake2 service
May 16 11:41:05 ubuntu echo[1800]: I am stopping the fake2 service
root@ubuntu:/etc/systemd/system# ps aux | grep fake*
root      1809  0.0  0.0  13688  2272 pts/8    S+   11:41   0:00 grep --color=auto fake.service
root@ubuntu:/etc/systemd/system#

as you can see the fake2 service is really only two lines. And when I grep for the service via ps I can't fine it. I guess it is because it has finished running. I am wondering how can I change it so that I can keep it running?

thanks

i am a musician so i wanted to install ubuntu studio to see what it was like. It said i needed to download the iso file and burn it to dvd. i did that. now it says that I should reboot the computer and it will start from the disk for a fresh install of my whole system. is this right? i only wanted a program not my sytem rebooted and re installed. does ubuntu do this each time you install a program? jesus!

Hello to everyone!

I was working on a linux server before few weeks. There was a grub/keyboard issue. If no keyboard is attached (ps port) the grub isn't loading the operating system. If the keyboard is attached the grub is loading the operating system by default without any keyboard interaction.

The difference is only that there is a keyboard attached. Thats all.

I was searching on the web and one thing came along: "turn on/off 'stop on errors' feature in your bios.". Maybe its this, but tonight I'm not able to check if its this becuase the server is in a remote location.

However I would like to hear what you think of this problem.

Have a good time!

Help!! In 12.04.5 Ubuntu, the /boot directory was full and had a lot of duplicate files from different dates, some I thought were unnecessary headers of updates. However, one series of files was called vmlinuz-3.2.0-29-generic. I moved all the files to /obsolete_files. I rebooted after having trouble upgrading packages (I think this is a second problem with this machine). I now get the following prompt.
grub rescue>

Is there a way to access the directory system so that I can move those files back? I really only need to retrieve one or two files off the system.

Code:

grub rescue>ls
(hd0) (hd0,msdos5) (hd0,msdos1) (fd0)

It doesn't under boot, or insmod. I can set prefixes. Am I doomed?
