ⓘ Alire has selected automatically this toolchain:
   gprbuild=22.0.1
   gnat_native=14.2.1
You can select a different toolchain at any time with `alr toolchain --select`
Download will start now:
Press Enter to continue or Ctrl-C to abort

If I Enter:

ubuntu@ubuntu-fc-uvm:~/sandbox/hello_1.0.2_5715870b/alire$ find / -iname 'gprbuild_*' 2>/dev/null
/home/ubuntu/.local/share/alire/toolchains/gprbuild_22.0.1_24dfc1b5
/tmp/.local/share/alire/toolchains/gprbuild_22.0.1_24dfc1b5

It really wants to install in /tmp... What am I doing wrong? Thx.

Thanks. Also of interest, alr version (note: not alr --version… :S)
