I tried to install NetBeans 7.2 from a downloaded .sh file, but experienced problems. Here's text from the Terminal, which shows what I did and what happened: hridesh@ubuntu:~$ cd Desktop/ hridesh@ubuntu:~/Desktop$ cd full\ netbeans\ 7.2\ for\ linux\ in\ .sh\ format/ hridesh@ubuntu:~/Desktop/full netbeans 7.2 for linux in .sh format$ chmod +x netbeans-7.1.2-ml-linux.sh hridesh@ubuntu:~/Desktop/full netbeans 7.2 for linux in .sh format$ ./netbeans-7.1.2-ml-linux.sh Configuring the installer... Searching for JVM on the system... Extracting installation data... Installer file /home/hridesh/Desktop/full seems to be corrupted Why does the message Installer file /home/hridesh/Desktop/full seems to be corrupted appear? Is this file actually corrupted or something else going wrong?
