I need to install Openjdk 21.0.5 or a later version. Nothing i do seems to work. I have downloaded the file into my download folder, but can't seen to get it to install.
Does anybody know where I can get step by step instructions on how to update this app?
Is this a .deb File? If yes, did You tried it with using Gdebi to install it? And when You install it, what Problems do You have in Detail? Do You get any Error Messages?
I saw that Openjdk is available in the Repo's in Version 21.0.6. So, You could take this. You could install Synaptic with the Terminal Command sudo apt install synaptic and then open it (You have to type in Your Password) and then search for openjdk-21 and You get a List of Packages.
When I do sudo apt install synaptic will I get a list of packages available? Then, do I just click on the package I want to install?
Synaptic is a GUI Package Manager.
When you run sudo apt install synaptic, this will install that package manager to your system.
Once installed, you can launch it from the App Menu (Start Menu) or from terminal by giving its executable name: synaptic
The GUI Synaptic package manager window will open. At the top ios a Search entry field.
In that, you can put (or paste in)
openjdk-21
and hit enter. This will then display a list of packages for that search term. You can click on (checkmark) which package or packages to install, then click the Apply button at the top to install openjdk.
When I put in "install synaptic", I get:
Install: missing destination file operand after "synaptic".
Do I need something more?
You have to type:
sudo apt install synaptic
and then type in Your Password.
