Can't install Java on Ubuntu Server 20.04.3 LTS

Question

So when I go to paste in:

sudo add-apt-repository ppa:linuxuprising/java

It says:

N: Ignorerar filen ”linuxuprising-” i katalogen ”/etc/apt/sources.list.d/” eftersom den inte har en filändelse

It's in Swedish but it basically ignores a file because it hasn't got a file ending. After this, I get a bunch of warnings telling me some packages are configured multiple times. No matter what I type it's always ignoring a file from linuxuprising. What do I do?

The content of linuxuprising-java.list is deb http://ppa.launchpad.net/linuxuprising/java/ubuntu focal main. This normal?

Complete Error message:

I tried doing

sudo apt autoremove
sudo apt-get update 
sudo apt-get install openjdk-17-jdk.

That should remove unneeded packages, update the internal list of packages, and install OpenJDK. But when I try these none of them work, not even the apt-get update. Here is the error I get:

filip@filip:~$ sudo apt autoremove
E: Malformed entry 1 in list file /etc/apt/sources.list.d/linuxuprising.list (Suite)

The error looks a little different now after I added a file extension to the linuxuprising directory.

Based on the results, I'd venture that you will need to edit your linuxuprising-java.list file to comment out (or remove) the duplicates. Which version of Ubuntu are you running? — matigo, Jan 04 '22 at 00:15
Does this answer your question? How can I fix apt error "W: Target Packages ... is configured multiple times"? — guiverc, Jan 04 '22 at 00:29
Does this answer your question? How do remove "Ignoring file in directory /etc/apt/sources.list.d/ as it has an invalid filename extension? — karel, Jan 04 '22 at 00:33
Why aren't you just using the openjdk-[version]-[jre/jdk] packages? What are you trying to do with a PPA? — cocomac, Jan 04 '22 at 03:35
I tried using the links karel and guiverc provided but it says that the file or directory doesn't exist when I paste in the command. — ItzFoil, Jan 04 '22 at 19:54
I'd be real careful adding off the wall repo's...Esp. with the log4j exploit. Follow @cocomac 's advice! — EODCraft Staff, Jan 04 '22 at 20:00
cocomac and @EODCraft Staff, I have already tried and I get the same message — ItzFoil, Jan 04 '22 at 20:05
@ItzFoil What exact command are you using to install OpenJDK? — cocomac, Jan 04 '22 at 20:07
@ItzFoil Don't paste in random commands. Understand what they do. — vidarlo, Jan 04 '22 at 20:28
@cocomac I've tried basically every command I can get my hands on. At last, I got Java 17 installed but the invalid file extension error remains. — ItzFoil, Jan 05 '22 at 14:09
Try these commands: sudo apt autoremove && sudo apt-get update && sudo apt-get install openjdk-17-jdk. That remove un-needed packages, updates the internal list of packages, and installs OpenJDK. [edit] your question to include what happens then — cocomac, Jan 05 '22 at 14:52
Please [edit] your question to include the output of cat /etc/apt/sources.list and ls /etc/apt/sources.list.d/ — Error404, Jan 08 '22 at 14:09

N: Ignorerar filen ”linuxuprising-” i katalogen ”/etc/apt/sources.list.d/” eftersom den inte har en filändelse

This message tells you that the file /etc/apt/sources.list.d/linuxxuprising- is ignored by apt as it doesn't have an extension.

Give the file an extension:

sudo mv /etc/apt/sources.list.d/linuxuprising- /etc/apt/sources.list.d/linuxuprising.list

For future reference, change the language to English before submitting error messages. I happen to be norwegian, and understand swedish well enough, but for most people interpreting that error message is somewhat difficult.

To get errors in english, simply prepend the command with LANG=c.

Doing this throws a bunch of errors for me
