I got to error installing pg gem

Question

I'm on Ubuntu 10.04, how to fix this error?

When I use bundle install command, this install the necessary gems for run the app with rails s.

But "bundle install" command fails too.

I don´t understand the console prompt, can somebody help me?

When I used the sudo apt-get install libpq-dev, I´m getting the following error:

antonio @ antonio-desktop: ~ / Downloads / ECOZAP $ sudo apt-get install libpq-dev
[sudo] password for antonio: 
E: Failed to lock / var / lib / dpkg / lock - open (11: Resource temporarily unavailable) 
E: Unable to lock the administration directory (/ var / lib / dpkg /), maybe there is another process using it?

@thorstenmüller I´m see your question, I have edited the main post. — Antonio Morales, Feb 03 '14 at 12:59
@FrankyCutty: This is more an System issue than anything with programming or Rails. See those questions with similar problems (read carefully, this is a bit strange maybe uless you have other programs running right now): http://askubuntu.com/questions/163030/cannot-open-lock-file-var-lib-dpkg-lock-permission-denied-even-using-sudo & http://askubuntu.com/questions/15433/how-do-i-fix-a-could-not-get-lock-var-lib-dpkg-lock-problem & http://ubuntuforums.org/showthread.php?t=2134172 — thorsten müller, Feb 03 '14 at 13:06

All you have to do is close any other package manager that is locking apt and install libpq-dev again.
