Problems with RPM (JRE)

Question

I'm trying to install a JRE on Ubuntu 10.04, but I failed:

oneat@oneat-desktop:~/Downloads$ sudo rpm -i --force-debian jre-6u21-linux-i586.rpm
error: Failed dependencies:

How can I work around that?

Edit: I tried Riccardo's answer, but it still doesn't work:

Those are only some of the errors:

Answer 1

Since you're running Ubuntu, can't you just install a JRE that comes from Ubuntu repositories? E.g., sudo apt-get install sun-java6-jre (which is presently at version 6.20dlj-1ubuntu3).

If you still need to go down the RPM route, you have two options:

1. tell rpm to ignore those dependencies (rpm --nodeps -i ...), since all those listed are programs that are already installed on a standard Ubuntu system. (The only mismatch is gawk, which is /usr/bin/gawk on Ubuntu, but /bin/gawk in the dependency output; you can either make symlink -to be on the safe side- or just ignore it and hope the JRE scripts do not hard-code the path to gawk.)

2. Use alien (sudo apt-get install alien) to convert the .rpm file into a .deb one; this should also fix dependencies or let you correct them.
