安装最新的Java

我使用的是 Fedora 39 KDE。我JDownloader2Setup_unix_nojre.sh从以下位置下载了“ ”文件https://jdownloader.org/jdownloader2。

安装程序不起作用。

./JDownloader2Setup_unix_nojre.sh 
Starting Installer ...
Could not display the GUI. This application needs access to an X Server.
*******************************************************************
You can also run this application in unattended mode without
access to an X server by passing the argument -q
*******************************************************************

“目录名称不能包含空格。”错误：

./JDownloader2Setup_unix_nojre.sh -q
Starting Installer ...
The installation directory has been set to /home/user/jd2/JDownloader 2.
The directory name must not contain spaces.

我能够让无人值守的安装程序工作（但不是 GUI 模式）。

安装最新的Java

安装JDownloader后，出现“java.lang.UnsatisfiedLinkError：无法加载库：/usr/lib/jvm/java-17-openjdk-17.0.9.0.9-3.fc39.x86_64/lib/libawt_xawt.so” “OpenJDK 17 上出现错误，所以我不得不切换到最新的 OpenJDK 22。

# Install latest OpenJDK.
sudo dnf install java-latest-openjdk-devel.x86_64 java-latest-openjdk.x86_64

# Switch to latest OpenJDK.
sudo alternatives --config java

# Confirm Java version.
java --version

以无人值守模式安装

要使用无人值守模式，您需要创建并提供一个“ response.varfile”文件。

“ response.varfile“ 文件：

sys.fileAssociation.launchers$StringArray="26","26","26","26","26"
sys.languageId=en
customTab$Boolean=false
customBasic$Boolean=true
sys.installationDir=/opt/JDownloader
customSearch$Boolean=false
customHomepage$Boolean=false
executeLauncherAction$Boolean=false
sys.fileAssociation.extensions$StringArray="dlc","jdc","ccf","rsdf","metalink"
installFM=skip

设置“ sys.installationDir”。例如我安装到“ /opt/JDownloader”。

# Create JDownloader installation directory.
sudo mkdir /opt/JDownloader
sudo chmod 777 /opt/JDownloader

./JDownloader2Setup_unix_nojre.sh -q -varfile "response.varfile"

成功：

Starting Installer ...
The installation directory has been set to /opt/JDownloader.
