I have a newbie question. On Linux, Alire is simply provided in an archive. So to update Alire I can just download a newer version and unpack the archive. But how do I update the installed toolchain(s) with Alire?

I think that `alr update` is project related and not what I want.

Hey, I think these two commands can be used to first update the index and then select the latest toolchain:

```
alr index --update-all 
alr toolchain --select

```

It seems that `alr toolchain --select` runs `alr index --update-all` automatically. At least with Alire 2.1.0 running on Debian 12.10 :

```ada
marcus@lovelace:~$ alr toolchain --select
The index can be periodically refreshed to make available recently published crates. 
Do you want Alire to go online without asking in the future? 
(You can update manually with `alr index --update-all` at any time.)
