Hi @jvelilla
Thanks for posting this issue.

Seems like something with gcc.
Could you please help confirm if you have installed glibc-2.31 on your machine?
You may refer to this to learn more about this.

Just for info updating Ubuntu installation fix the issue.

Before the update, I had GCC version

GCC version:

$ gcc --version
gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008
Copyright (C) 2019 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

After the update, GCC Version

gcc --version
gcc (Ubuntu 9.3.0-10ubuntu2) 9.3.0
Copyright (C) 2019 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

So with this new GCC version and glibc-2.31 I was able to bootstrap vcpkg
