I think this was unintended: useradd -g sets the gecos field to "100".
Probably we meant to use -G to set the ipfs user group.

-G does not take gids, so it needs to be set by name.
The group with gid 100 is "users".

Additionally, since we install the ca-certificates package
(which is already installed), at least we should attempt to update it
to get the latest version of certs.
