I am new to Ubuntu and i was trying to install the restricted extras using this command
sudo apt-get install ubuntu-restricted-extras
In the end there was a licence aggrement page which it asked me to agree but the OK button did not get selected even when i clicked on it so i closed the terminal but now when i start the terminal and try to install other softwares it is not allowing me to install and it is giving me the following error:
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
Please tell me what to do now. Can i resume where I left the installation?
