Oracle Corporation (VirtualBox archive signing key) info@virtualbox.org Common Troubleshooting Download VirtualBox for Linux Hosts

wget -O- https://www.virtualbox.org/download/oracle_vbox_2016.asc | sudo gpg --dearmor --yes --output /usr/share/keyrings/oracle-virtualbox-2016.gpg Use code with caution.

The most common way to use this command is by "piping" it directly into your system's keyring manager to automate the security setup. For Debian, Ubuntu, and Linux Mint (Modern Method)

When you add a third-party repository like VirtualBox.org to your Linux system, your package manager (like apt or dnf ) needs a way to ensure the software hasn't been tampered with. The .asc file contains a digital signature that confirms the code was officially released by Oracle Corporation.

Without this key, you may encounter "GPG signature verification" or "Bad GPG signature" errors during installation. How to Use the Command

The command wget https://www.virtualbox.org/download/oracle_vbox_2016.asc is used to download the official required to verify the authenticity of VirtualBox software packages. Since 2016, Oracle has used this specific key to sign packages for Debian-based distributions, and it is now also used for RPM-based systems like Fedora and RHEL. Why This Key is Necessary

For maximum security, you should verify that the key you downloaded matches the official Oracle fingerprint:

Newer versions of Debian-based systems prefer keys to be stored in /usr/share/keyrings rather than the deprecated apt-key .

After running this, you can add the repository to your sources list, ensuring it points to the new keyring file. For Fedora, RHEL, and Oracle Linux

How it works?

Java GC Tuning is made to appear as rocket science, but it's a common sense!

  • 1

    Enable GC Logs

    You can enable GC log by passing following JVM arguments:
    Until Java 8: -XX:+PrintGCDetails -Xloggc:<GC-log-file-path>
    Java 9 & above: -Xlog:gc*:file=<gc-log-file-path>

How to enable Java GC Logging?

For Java 1.4, 5, 6, 7, 8 pass this JVM argument to your application: -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:<file-path>

For Java 9, pass the JVM argument: -Xlog:gc*:file=<file-path>
file-path: is the location where GC log file will be written

GCeasy couldn't parse my GC Logs?

We do support all of the GC log formats irrespective of the JVM version, JVM provider, GC algorithms, memory settings.

However if we don't support your format, Please report it to . We will fix it.

Can I look at sample GC log analysis reports?

Sure. Here are some sample reports generated by GCeasy:
