The .dmg is Apple-Silicon only. Choose Java JAR above instead and install Java 11.
Linux
Installing the .deb
Double-click Clamperz.deb to open Software Install, or run: sudo apt install ./Clamperz.deb. Then launch Clamperz from your apps menu.
Dependency errors
Run: sudo dpkg -i Clamperz.deb, then sudo apt-get install -f to install any missing dependencies.
On ARM Linux, Fedora, or Arch?
The .deb is for 64-bit (amd64) Debian, Ubuntu, and Mint. On other distributions or ARM machines, choose Java JAR above and install Java 11.
Java JAR
Install Java first
The Java JAR needs Java 11 installed separately. Get Temurin 11, then double-click ClamperzLauncher.jar.
Get Java 11 →Double-clicking does nothing
Open a terminal in the download folder and run: java -jar ClamperzLauncher.jar. This also shows any startup error.
“Unsupported Java version”
Use Java 11 (recommended). The client supports Java 11–22; Java 10 and older or 23 and newer are not supported.
