HI, I’ve being trying to install Mojo using the instructions [here](https://docs.modular.com/mojo/manual/get-started/). All goes well until I try to run mojo when it crashes immediately with > 2343 external/tcmalloc+/tcmalloc/system-alloc.h:575] MmapAligned() failed - unable to allocate with tag (hint=0xc0440000000, size=1073741824, alignment=1073741824) - is something limiting address placement? > 2343 external/tcmalloc+/tcmalloc/system-alloc.h:582] Note: the allocation may have failed because TCMalloc assumes a 48-bit virtual address space size; you may need to rebuild TCMalloc with TCMALLOC\_ADDRESS\_BITS defined to your system’s virtual address space size > 2343 external/tcmalloc+/tcmalloc/arena.cc:59] CHECK in Alloc: FATAL ERROR: Out of memory trying to allocate internal tcmalloc data (bytes=131072, object-size=16384); is something preventing mmap from succeeding (sandbox, VSS limitations)? > Aborted My exact OS details given by cat /etc/os-release are > PRETTY\_NAME=“Debian GNU/Linux 12 (bookworm)” > NAME=“Debian GNU/Linux” > VERSION\_ID=“12” > VERSION=“12 (bookworm)” > VERSION\_CODENAME=bookworm > ID=debian > HOME\_URL=“[https://www.debian.org/](https://www.debian.org/)” > SUPPORT\_URL=“[Debian -- User Support](https://www.debian.org/support)” > BUG\_REPORT\_URL=“[https://bugs.debian.org/](https://bugs.debian.org/)” According to file /lib/systemd/systemd the Raspberry Pi architecture is > /lib/systemd/systemd: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, BuildID[sha1]=4d5bcc858178dfbbffc8f60b0e2d8200c03c3712, for GNU/Linux 3.7.0, stripped What is going wrong? ---

Hello, 🎉 `Ubuntu LTS 24.04 server` is available for pi, this one work like a charm out of the box! (available even in the rpi-imager) #### Webpage: > **[Install Ubuntu on a Raspberry Pi | Ubuntu](https://ubuntu.com/download/raspberry-pi)** > > Ubuntu is an open-source operating system for cross-platform development, there's no better place to get started than with Ubuntu on a Raspberry Pi ⬆ Amazingly, most PI’s are certified devices for 24.04 LTS. #### Tutorial: > **[How to install Ubuntu Server on your Raspberry Pi | Ubuntu](https://ubuntu.com/tutorials/how-to-install-ubuntu-on-your-raspberry-pi#1-overview)** > > Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. #### My experience: Ubuntu server worked out of the box, just install pixi, and that’s it! (Tested on the pi zero 2W, `RAM: 512Mb`) Also, LTS means long standing support 🥳 #### Customizing an OS kernel ? Yep, there are tutorials on PI website to customize an kernel, so it can be built with VA\_BITS 48. That’s good! This is too much for me, so i just use Ubuntu 😃 ---
