Permissions issue? Unable to create items in different areas of filesystem.

wolvinedragon · 09-25-2009, 09:47 AM

Hey there, I have finally installed Ubuntu Netbook Remix on a HP 1030NR and am trying to get it to work for my wife.

I have successfully installed Flash for firefox, working ok.
I have downloaded java to the desktop (default save location)

The instructions on the java page are telling me to make a .bin file executable (done), run it in a folder such as /usr/. I am unable to create any folders in this area, logged in as the only user on the computer.

I did create a directory in (/home/<username>/) naming it java. I copied the file from the desktop to there, changed permission to enable execution in the gui menu, and ran the file from the terminal. The file extracted how it was supposed to.

Next, I am told to create a .so file in the firefox plugins directory. I get access denied error when I use (ln -s /home/<username>/java/jre1.6.0_16/plugin/i386/ns7/libjavaplugin_oji.so) from the firefox plugin directory.

I noticed I also have no permissions to create or modify items in this directory.

So the root of the question would be "how the heck do I give myself permission to edit system directories"

Thanks in advance.

EDIT: I removed the chmod command to prevent any mishaps.

Please note, that if you edit system directories or change their permission, many times this could be hazardous since they expect their default permission settings. What you can do is use "sudo" before a command to gain temporary root privilege.

Btw, please use synaptic [Syste,m->Administration] and search for softwares, e.g.-> java, and then install.

Ok, I looked through Synaptic Package Manager, searching for java in names and descriptions. All I got was:
libgtksourceview2.0-common
libgtksourceview-common
gdb
britty
libdbus-1-3
dbus

the descriptions range from a syntax highliting widget to a debugger, to a braille program, to a messaging system.

I tried browsing the sections one bit at a time and got even more confused... such as there being 4 sections of communication with multiverse, restricted, and universe as alternate sections.

Just when I think Linux is looking easier, it throws another oddball at me (and I'm sure the above is nothing compared with what knowledgable Linux users do). I'm gonna start looking for some courses in Linux so I don't flood the forums here.

Hi! wolvinedragon, you might need to enable your repositories.
Just read a bit about it here and you will learn+figure out the solution yourself.

Repositories
Medibuntu
Restricted Formats

This will help you get all the audio, video codecs and a lot more! Trust me Linux isn't that hard so don't give up.

There is no need to do that; if install calls for something like this request somewhere something is wrong in the first place. There is a .deb install package for java and it should save you from building the package itself. Just use google. Ubuntu has excellent repos too. Or you may try install open office suite this will use install java for its need.

Use the Search window or Press Ctl+F at Synaptic, enter your searching word, this will save you time.

Nice attitude. You will learn much reading offline, download this Tutorial. There are also good learning sites for linux commands, and a lot more in this rich site.

Hope this helps.
Good luck.

Not sure if this will work for you, but it did for me:
Navigate to this page.
Firefox will complain about missing plug ins, install them

Yes, it's that easy

It's in synaptic. Start synaptic, left click the first entry in the top-right pane (2vcard); start typing sun-java6; the first entry is sun-java6-bin

I have installed sun-java6-bin and sun-java6-jre. I've also installed sun-java6-jdk but unless you want to do development, you probably don't need it. There is also sun-java6-plugin which probably is what you're are looking for for use with webbrowsers.
It will probably be enough to only install the latter if you need it for the webbrowsers; other stuff will automatically be installed if necessary.

PS You're not the only one who was looking for it; it took me a while till I got clever enough to realize that it came from sun
