I am facing problem while installing sagemath. I am unable to decompress this "Ubuntu_14.04_LTS_sage-6.7-i686-Linux.tar.lrz" version of ubuntu. Which command i need to run to decompress the file.

[avi kaur]

ubuntu decompress lrz

?

Sorry John I don't know What is this? I am totally new to this environment.

[Vincent Delecroix]

Do you know what is a console?

[avi kaur]

Yes  Vdelecroix
I feel It is "ctrl+alt+f1".

[Vincent Delecroix]

Nope. There should be an application called "console" or "terminal". It
would be better if you find somebody that explain that to you in live.
You can also have a look here

[avi kaur]

Ok
I am going to try this one, too on ctrl+alt+f1 or t.

But how i would exit from this mode?

All developers are very helpful

Thank you

Actually ctrl alt f7 converts the whole desktop to a terminal. Then you have to login. When done ctrl alt f7 toggles back to a GUI desktop. It takes a moment.

Ok I try

Thank you :)

tar --lzma -xvf sage...tar.gz

[Jorge Garcia]

ctrl alt t opens a terminal with GUI desktop unaffected.

[avi kaur]

Sir It displays that It is not a tar file. Moreover, The version I want to install has ".lrz" extension.

Did you do a chksum on your download? Maybe download another copy. Sounds like a corrupt file.

A "console" is HMI for UNIX or linux computer ... long time ago, the "console" was software handling what you type at keyboard and displaying on a screen the result.

Nowadays computers handle many users and there are more than one "window" displayed on physical screen : software handling requests are now named "terminal" ..."console" is the main "terminal", handling HMI of the main user and usually displaying internal computer messages.

If your computer is a Linux PC (operating system Ubuntu?) then the "console" is running, sometimes in text non graphics mode, or you can have it on you desktop graphic display....usually type some magic keyboard keys to pop it up.

If your computer is a PC with internet browser and you have remote access to the actual computer where is your file (for example sage cloud) then the "console" is running on the remote computer....and you have on meu in the browser window to start a "terminal".

I think your computer is Linux PC because you want (in your 1st post) to download and install sagemath.

1. start a terminal on your computer, home-directory of user
2. check if you have "lrzip" using terminal commands : simply "lrzip" or "which lrzip"
3. if you don't have, download and install "lrzip"...source is at  https://github.com/ckolivas/lrzip..and browsing the web a little you can find binary distribution for you computer (I suppose 32 bits because of 686 in flename .lr...,  your computer can be 64 bits too)
4. change directory, and unzip with "lrzip -d Ubuntu_14.04_LTS_sage-6.7-

i686-Linux.tar.lrz"
5. follow the sagemath install hints

sudo apt-get install lrzip

lrzuntar -d file.tar.lrz    or lrztar -d file.tar.lrz

HTH

[Harald Schilly]

The download page itself tells you to

1. install lrzip:
$ sudo apt-get install lrzip
(or via synaptic)

2. $ lrzuntar *.tar.lrz

Hope this helps, Harald

[avi kaur]

I am fed up with that. I run the lrzuntar -d. It displays the following:


avi@avi-HP-G42-Notebook-PC:~$ lrzuntar -d Ubuntu_14.04_LTS_sage-6.7-i686-Linux.tar.lrz
Decompressing...

tar: Exiting with failure status due to previous errors
avi@avi-HP-G42-Notebook-PC:~$

I tried this one also "lrzip -d" but still :(

avi@avi-HP-G42-Notebook-PC:~$ lrzip -d Ubuntu_14.04_LTS_sage-6.7-i686-Linux.tar.lrz
Output filename is: Ubuntu_14.04_LTS_sage-6.7-i686-Linux.tar

Fatal error - exiting
avi@avi-HP-G42-Notebook-PC:~$

and tried this also "lrzuntar *.tar.lrz. It shows:

avi@avi-HP-G42-Notebook-PC:~$ lrzuntar *.tar.lrz
Decompressing...

Maybe you are "fed up" but ...nobody except you can read with your eyes :

avi@avi-HP-G42-Notebook-PC:~$ lrzip -d Ubuntu_14.04_LTS_sage-6.7-

i686-Linux.tar.lrz
Output filename is: Ubuntu_14.04_LTS_sage-6.7-i686-Linux.tar
Failed to create Ubuntu_14.04_LTS_sage-6.7-i686-Linux.tar
File exists
Fatal error - exiting
avi@avi-HP-G42-Notebook-PC:~$

...and guess what ? .... the fileUbuntu_14.04_LTS_sage-6.7-i686-Linux.tar  exists

Then please, remove it (I hope you know the "rm" command)...and try again.

I guess other commands failed because lrzuntar has same parameters than tar, mainly -f specifying you want unzip and extract from a file rather a device.....please again, RTFM (aka 'use man") for command (new for you).

Dominique.

I will follow you, Sir
