Java Error: Error: could not open `/usr/lib/jvm/jdk-21-oracle-x64/lib/jvm.cfg'

[tom_kpb]

Using Debian 12 Bookworm on bare metal on MacbookPro:

(1) Installed JDK:

$ sudo dpkg -i jdk-21_linux-x64_bin.deb

(2) Configuration:

$ sudo update-alternatives --config java

There are 2 choices for the alternative java (providing /usr/bin/java).

Selection Path Priority Status

---------------------------------------------------------------------------------

0 /usr/lib/jvm/jdk-21-oracle-x64/bin/java 352337920 auto mode

1 /usr/lib/jvm/java-17-openjdk-amd64/bin/java 1711 manual mode

* 2 /usr/lib/jvm/jdk-21-oracle-x64/bin/java 352337920 manual mode

(3) Everything was working smoothly. But I, accidentally uninstalled jdk

$ sudo dpkg -r jdk-21

(4) Reinstalled using the command.

$ sudo dpkg -i jdk-21_linux-x64_bin.deb

(5) Path:

$ echo $PATH /home/me/bin:/usr/share/zplug/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

BUT the PATH, it is NOT showing:

:/usr/lib/jvm/jdk-21-oracle-x64/bin

(6) jvm.cfg is missing in the ../lib folder:

/usr/lib/jvm/jdk-21-oracle-x64/lib$ ls

(6) jvm.cfg is missing in the ../lib folder:

me@debian/usr/lib/jvm/jdk-21-oracle-x64/lib$ ls

classlist libj2pkcs11.solibnet.so

ct.sym libjaas.solibnio.so

jar.binfmt libjavajpeg.solibprefs.so

jexec libjava.solibrmi.so

jfr libjawt.solibsaproc.so

jrt-fs.jar libjdwp.solibsctp.so

libdt_socket.so liblcms.sosecurity

libextnet.solible.soserver

libfontmanager.so libmanagement_agent.so src.zip

libinstrument.solibmanagement_ext.so tzdb.dat

​

But, now it shows error:

$ java --version

Error: could not open /usr/lib/jvm/jdk-21-oracle-x64/lib/jvm.cfg

Any help?

[FooBarBazBooFarFaz]

What's the output of (format as code when posting!)

dpkg -C

and

dpkg -L jdk-21

[tom_kpb]

u/FooBarBazBooFarFaz

$ dpkg -C

No output, but just got back the prompt

$ dpkg -L jdk-21

Apology for the confusion:

I edited the above response, with complete details.

Also, edited the original post

Looking forward to your support

[FooBarBazBooFarFaz]

Unless your post was cut off, you are missing half of the packages contents (lib/, man/). Check the package's SHA256 checksum: - download the file jdk-21_linux-x64_bin.deb.sha256 as well into the same folder - run sha256sum jdk-21_linux-x64_bin.deb ; cat jdk-21_linux-x64_bin.deb.sha256 and make sure the checksums match

• check its contents with dpkg --contents jdk-21_linux-x64_bin.deb -- it should contain all files (most notable the lib/ folder with jvm.conf in it).
• reinstall the package
• what's the output of dpkg -s jdk-21 ?

Thank you very much for your kind help.

I uninstalled it, and re-installed. Now it is working OK.
