steep stirrup Dec 29, 2022, 2:33 PM

#

maybe remove 17

#

and install 16

#

it gives me this Unsupported Java detected (61.0). Only up to Java 16 is supported.

#

since its only till 16

kind remnant Dec 29, 2022, 2:35 PM

#

i did that i removed java 17 apt remove java-common (i did this because sudo apt remove java-open-17 or that thing you told me to remove java 11 did not work) and installed it with the 16 command but it installed 17

#

is he trying to install java 16?

steep stirrup Dec 29, 2022, 2:44 PM

#

yeah

#

here

#

you might need to change directory though

#

https://jdk.java.net/archive/

#

go down and go to jdk 16

#

16 GA (build 16+36)

#

this one

#

then go to the place you downloaded it

#

explorer

#

then right click open terminal there

#

then do

#

tar zxvf openjdk-16_linux-x64_bin.tar.gz

#

now you will get a jdk-16

#

folder

#

done

#

just change directory of java

kind remnant Dec 29, 2022, 2:46 PM

#

im just gonna reinstall the server with another os just mark this form as unsolved and leave it open

steep stirrup Dec 29, 2022, 2:47 PM

#

you will get into other problems but as you wish

steep stirrup Dec 29, 2022, 2:47 PM

#

steep stirrup ```tar zxvf openjdk-16_linux-x64_bin.tar.gz```

this is the solution if you want to try later.
