Failed to install via curl | bash: line 14: BASH_SOURCE: unbound variable

[dflock]

Describe the bug

I tried installing via cargo and that didn't work (#56), so I tried using the curl | bash method and that failed too.

To Reproduce

$ curl -sfSL https://raw.githubusercontent.com/innobead/huber/master/hack/install.sh | bash

bash: line 14: BASH_SOURCE: unbound variable
++(${BASH_SOURCE}:${LINENO}): ${FUNCNAME[0]:+${FUNCNAME[0]}(): }uname
bash: line 14: BASH_SOURCE: unbound variable

Expected behavior

Should work.

Environment

• OS version
  • Linux duncan-desktop 5.15.0-48-generic #54-Ubuntu SMP Fri Aug 26 13:26:29 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
  • Ubuntu 22.04.1 LTS
  • GNU bash, version 5.1.16(1)-release (x86_64-pc-linux-gnu)
• Huber version
  • n/a

Doing what the bash script does, manually, works fine - huber seems to work fine.
