Hi everyone,

I'm new to Ubuntu and I tried to install OpenFoam by following the steps on the website but I got this one error after the third step I can't fix about packages having unmet dependencies. I'll just go ahead and copy that part:

The following packages have unmet dependencies:
openfoam211 : Depends: csh but it is not installable
Depends: libopenmpi1.3 but it is not installable
Depends: libptscotch-5.1 but it is not installable
Depends: libscotch-5.1 but it is not installable
Depends: libscotch-dev but it is not installable
Depends: libopenmpi-dev but it is not installable
Depends: openmpi-bin but it is not installable
Recommends: libptscotch-dev but it is not installable
E: Unable to correct problems, you have held broken packages.


Thanks in advance!

Greetings Didac and welcome to the forum!

The error message is a bit vague... I'm guessing you manually downloaded the Deb packages?

If not, did you run:

sudo apt-get update
sudo apt-get install openfoam211

The first command, did it give any error messages?

Best regards,
Bruno

Bruno, sorry for not specifying more,

In order to install OpenFoam I followed the steps on the following website:
http://www.openfoam.org/download/ubuntu.php

After the first two steps i got the following message on the terminal window:
ubuntu@ubuntu:~$ VERS=$(lsb_release -cs)
ubuntu@ubuntu:~$ sudo sh -c "echo deb http://www.openfoam.org/download/ubuntu $VERS main > /etc/apt/sources.list.d/openfoam.list"

I think I fixed the problem by going to software up to date, settings, other software and unchecking CDrom with Ubuntu 12.04 'Precise Pangolin'

Then I went ahead with the second step again and it worked fine:

Thanks again Bruno.

Hi Didac,

Mmm... apparently you disabled the universe repositories, which are needed for scotch and other packages. E.g.: http://packages.ubuntu.com/precise/scotch

Package: scotch (5.1.12b.dfsg-1) [universe]

Best regards,
Bruno

[pirom]

Hello, I am experiencing a similar issue in installing OpenFoam where the following dependencies cannot be installed after a "sudo apt-get install openfoam220" (see below). I see from a number of posts that the universe repositories need to be enabled, which can be done by uncommenting lines in the /etc/apt/sources.list file. Not only is this file blank, but I am unable to modify the file (even if doing a w! in VI). Any ideas?

Thanks,
M.P.

Greetings M.P.,

If the file "/etc/apt/sources.list" is empty, then use the default one: https://help.ubuntu.com/12.04/server...iguration.html

Best regards,
Bruno

[pirom]

Thank you for the response. I am unable to modify the file...VI returns "E505: "/etc/apt/sources.list" is read-only (add ! to override)" and if I were to force save (i.e., "w!"), VI returns "'/etc/apt/sources.list' E212: Can't open file for writing".

Any ideas?

Thanks.

[wyldckat]

Hi M.P.,

Try one of the following lines:

sudo vi /etc/apt/sources.list
sudo nano /etc/apt/sources.list

More about these commands:

• sudo - grants super-user powers for the application to be executed.
• nano - it's a terminal based text editor tha is a bit easier to use than vi.

For more information: https://help.ubuntu.com/community/UsingTheTerminal

Best regards,
Bruno

[pirom]

Thank you Bruno for the response. I very much appreciate it.

Using the default sources.list file (that you suggested) and then doing a sudo apt-get update results in the following error:

W: GPG error: http://extras.ubuntu.com precise InRelease: File /var/lib/apt/lists/partial/extras.ubuntu.com_ubuntu_dists_precise_InRelease doesn't start with a clearsigned message

E: Some index files failed to download. They have been ignored, or old ones used instead.


Looking at a number of posts online, the common recommended solution is to remove the source list file and update, but this results in the same error. Another solution suggested by some online posts is to remove the links causing the errors in the source.lists file and then update. Commenting out the following lines from the sources.list file that you recommended:

## deb http://extras.ubuntu.com/ubuntu precise main
## deb-src http://extras.ubuntu.com/ubuntu precise main

Obviously, this does not result in an immediate error when updating apt. Then,

sudo apt-get install openfoam220

results in the following error:

Install these packages without verification [y/N]? y

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Then,

sudo apt-get install openfoam220 --fix-missing

results in the following error:

Failed to fetch http://www.openfoam.org/download/ubu..._0-1_amd64.deb Size mismatch
Unable to correct missing packages.
E: Aborting install.


Any ideas/advice would be much appreciated!

Thanks

[pirom]

...also, I noticed that the link for the binaries in the error message is for amd64, but I am using an intel64 machine. Maybe there is a mismatch there?

There are two types of Intel 64bit processors:

• x86_64, which basically amd64: http://en.wikipedia.org/wiki/X86-64
• IA64, which is a special 64bit processor that is mostly incompatible with x86: http://en.wikipedia.org/wiki/Itanium

You can confirm this by running:

uname -a

As for the other problem, try the following command:

ping ubuntu.com

Hit Ctrl+C when you get tired of looking at the ping responses

If it tells you that it takes "x.xxx ms" to reach the "ubuntu.com" server, then you have a working network access. If not, then your internet access is not properly configured.
