Maybe the JDK has a different version number than the JRE, I theoretise. In the meantime, I have also googled for JDK, since I assume that I need the Java SDK to get the compilers. "java vs java se", I google, but all I get are articles about how Java SE is different from something called Java EE. Odd, I think, didn't Oracle tell me just now that Java 8 was released in 2021? Oh, I see, they are talking about something called "Java SE". Huh, what's that, there are versions of Java up to 16? One article mentions that Java 8 has been deprecated for years. If I am up to date, why is Eclipse complaining, I wonder? So I google Java 11. Oracle offers me to download Java 8 Update 291, released April 2021. Updated it to 2021, and it tells me I need Java 11 or higher.
I had a 2019 version of Eclipse installed from last time I wanted to learn Java. I'm trying out some programming languages to perhaps get into (after previously primarily doing stuff with C#). I have downloaded jdk-11.0.7_linux-圆4_ and placed it into /var/cache/oracle-jdk11-installer-local, but now when I run sudo add-apt-repository ppa:linuxuprising/java I get an error Err:1 archive.ubuntu eoan InRelease Could not resolve 'archive.Okay, context. Nothing is in the java-11-oracle directory. Installed oracle-java11-installer-local package post-installation script subprocess returned error exit status 1Įrrors were encountered while processing:Į: Sub-process /usr/bin/dpkg returned an error code (1) When trying to install using Terminal, I receive this error: Oracle JDK 11 is NOT installed.ĭpkg: error processing package oracle-java11-installer-local (-configure): I have tried sudo dpkg -i jdk-11.07_linux-圆4_bin.deb but I get "dpkg: error: cannot access archive 'jdk-11.07_linux-圆4_bin.deb': No such file or directory". So I press Install again, and it says are you sure you want to remove it? If I click remove, it just disappears from Ubuntu Software. It shows up under the installed tab, but then it still says install on the far right column. When I double click the icon the Ubuntu Software Install page pops up, I hit install, but it never installs. deb file is saved in my Downloads folder. deb version of Java SE JDK from this site: This.
