Cannot install influxdb 1.8.9

Up to a week ago I was using Influxdb but I started getting an error:
Failed to connect to http://localhost:8086: Get http://localhost:8086/ping: dial tcp [::1]:8086: connect: connection refused
Please check your connection settings and ensure ‘influxd’ is running.

AS I could not fix it (after reviewing some solution) I decided to reinstall Influxdb.
I am using these commands:

wget https://dl.influxdata.com/influxdb/releases/influxdb_1.8.9_amd64.deb
sudo dpkg -i influxdb_1.8.9_amd64.deb

This is what I am getting:
sudo dpkg -i influxdb_1.8.9_amd64.deb
(Reading database … 129863 files and directories currently installed.)

Can anyone please help?
Thanks.
