bbduk error assigning memory

[Gastón Viarengo]

I'm using Ubuntu 20.04.2 LTS. I've installed bbmap (version 38.79+dfsg-1) through "sudo apt-get install bbmap". However, when running "bbduk.sh --version" or a script "bbduk.sh -Xmx..." (I've tried with -Xmx5g, -Xmx4g, -Xmx1g, -Xmx800m, -Xmx100m and without setting -Xmx on a 8 gb RAM machine) I get the following error:

/usr/bin/bbduk.sh: línea 344: /usr/share/bbmap/calcmem: No existe el archivo o el directorio
/usr/bin/bbduk.sh: línea 345: setEnvironment: orden no encontrada
/usr/bin/bbduk.sh: línea 346: parseXmx: orden no encontrada
/usr/bin/bbduk.sh: línea 350: freeRam: orden no encontrada
java -Xmxm -Xmsm -cp /usr/share/java/bbmap.jar jgi.BBDuk --version
Invalid maximum heap size: -Xmxm
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Downloading the package, untaring it and adding the path to the directory in the .bashrc file prompts the same error when running the above described commands. Also, the folder /calcmem does indeed do not exist.
