Welcome,

error indicates You don’t have file /usr/bin/genieacs-ui
Are You check other files /usr/bin/genieacs-[cwmp|ext|fs|nbi]? There should be symlink to other directory. Maybe someone remove one of symlink, if so just recreate it. If there is none of them maybe genieacs didn’t install correctly.

Ahh, and one more think, use for future “Preformatted text” for code/logs/etc.
`some text`
or
```some text
with multiple lines```
