Download latest release, v0.0.19, lunii-admin_linux_amd64.

Tried to run in Linux Mint and got this error:

/lunii-admin_linux_amd64: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./lunii-admin_linux_amd64)
./lunii-admin_linux_amd64: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by ./lunii-admin_linux_amd64)

Note: just tested and previous versions up to 0.0.17 work fine. Offending release is 0.0.18
