Slow boot time Ubuntu Server 20.04

Question

Ubuntu 20.04 webserver Platforms : Webmin/Virtualmin Hardware: i5-4570 + 8gb ram and 1 SSD

I had installed OpenMediaVault at some point on server and i purged it and removed ssd with the openmedia vault. I think boot time is affected by this. Here are some commands from logs:

systemd-analyze time

Results:

Startup finished in 5.827s (firmware) + 2.794s (loader) + 3.302s (kernel) + 1min 40.095s (userspace) = 1min 52.019s graphical.target reached after 1min 39.551s in userspace
