Installer displays following error message: root@netbeans:~# sh netbeans-7.2-ml-javase-linux.sh Configuring the installer... Searching for JVM on the system... Extracting installation data... Installer file /root/netbeans-7.2-ml-javase-linux.sh seems to be corrupted I tried another bundle installers and the message is always the same, therefore I don't think, that files are corrupted indeed.
check if the md5 sum of the downloaded file is the same as on the download page
