I had a problem with this. I was getting
sha256sum mismatch jdk-7u3-linux-x64.tar.gz
I checked the file in
/var/cache/oracle-java7-installer
and it looked like it was invalid
I was able to fix it by directly downloading the file from oracle, putting it in the cache directory and then editing
/var/lib/dpkg/info/oracle-java7-installer.postinst
and bypassing ths download and sha check
This problem just started happening today, I used the package successfully yesterday on a different computer
The problem is that the java download package is malformed and only contains an Unauthorized Download message and info.
It seems Oracle prevents direct downloads
Thanks – that solved the problem for me too – just had to put the jdk-7u3-linux-x64.tar.gz file into /var/cache/oracle-java7-installer/ and then comment out the code between ‘echo “Downloading…”‘
and ‘echo “Download done”‘ in the /var/lib/dpkg/info/oracle-java7-installer.postinst script.
how can i do that??
Use a text editor to open the file and put a “#” at the start of each line between ‘echo “Downloading…”‘
and ‘echo “Download done” in the file, then save it.
I had this problem too!

oracle-java7-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)
Pls help. I am facing the same problem here. I am not able to install any version of java, and my entire work has stopped because of this! 🙁 I am on Natty!
Hi Anthony, i make that change, it’s pass, and i need to comment the code for a “verify SHA256 checksum” but now a get this error:
mv: impossível obter estado de “jdk1.7.0_03”: Arquivo ou diretório não encontrado
dpkg: erro processando oracle-java7-installer (–configure):
sub-processo script post-installation instalado retornou estado de saída de erro 1
E: Sub-process /usr/bin/dpkg returned an error code (1)
Do you now how can i fix this?
I don’t speak spanish – can you translate that for me?
Also, I don’t know why you need to comment the code for verifying the SHA256 checksum… why are you doing that?
I found this and worked:
OK figured out how to install.
Download tar.gz from here: http://www.oracle.com/technetwork/java/javase/downloads/jdk-7u3-download-1501626.html
and place it to: var/cache/oracle-java7-installer
then open with text editor: var/lib/dpkg/info/oracle-java7-installer.postinst
and place # (or delete) in beginning of these lines: 74-107, 111-116
and then run again sudo apt-get purge openjdk*
try my answer above.
Anthony,
i need to comment the SHA256 checksum because give me a error and stop.
Here:
mv: can not get status “jdk1.7.0_03”: File or directory not found
dpkg: error processing oracle-java7-installer (- configure):
subprocess post-installation script returned error exit status 1
E: Sub-process / usr / bin / dpkg returned an error code (1)
falzer the error continue..
I had already tested this, yesterday, but doesn’t work.
maybe you commented something in post-installation that was not to be commented. have u tried it from beggining?
After installing repo I just install it from synaptic… 😉
It works.
I use this tuto to install and its works:
http://www.liberiangeek.net/2012/04/install-oracle-java-jdk-7-in-ubuntu-12-04-precise-pangolin/
$ cp /usr/lib/jni/libswt-*3740.so ~/.swt/lib/linux/x86
Hi…
After some errors and testing, i found out that following the proposal of falzer is the best solution.
Thanks for that falzer.
I followed falzer’s solution and still, I got this:
Download done.
sha256sum mismatch jdk-7u3-linux-x64.tar.gz
Oracle JDK 7 is NOT installed.

dpkg: dependency problems prevent configuration of oracle-jdk7-installer:
oracle-jdk7-installer depends on oracle-java7-installer; however:
Package oracle-java7-installer is not configured yet.
dpkg: error processing oracle-jdk7-installer (–configure):
dependency problems – leaving unconfigured
No apport report written because the error message indicates its a followup error from a previous failure.
Errors were encountered while processing:
that basically means that the checksum in the install script did not match,
you may have downloaded jre 7u4 instead of 7u3
This is what works for me
sudo rm /var/lib/dpkg/info/oracle-java7-installer*
sudo apt-get purge oracle-java7-installer*
sudo rm /etc/apt/sources.list.d/*java*
sudo apt-get update
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
Thanks to cga. That works for me too!
