Attempting to install Java 8

I'm trying to install java 8 so that I can mod borderlands 2 from epic but when I try to run the RPM to install java I get this error
warning: jre-8u441-linux-x64.rpm: Header V3 RSA/SHA256 Signature, key ID ad986da3: NOKEY
error: can't create transaction lock on /usr/share/rpm/.rpm.lock (Read-only file system)

Solution

I figured out how to do it, I had to add the command inside the single quotes to my bashrc file and then make a .desktop file for java so I could run jar files without using the terminal every time

I haven't heard of that before? How would I go about doing that?

Lily/Lilith/Tea/LukaOP•3/2/25, 9:41 AM

nvm, found it

now I can't seem to open the jar file I have with openjdk

i definitely installed it through brew but it doesnt seem to be recognized as an installed app

you need to open terminal and then

i guess i didnt install it correctly then

or I'm missing something

running the command it tells me to after installing seems to do nothing

Open a new window and it should update your path
