Nuclei is not getting updated

[HunterX461]

Nuclei version: v3.2.7

Current Behavior: while trying to update the nuclei to its latest v3.2.8 it is not updating and showing an error message 'flag provided but not defined: -update'

The nuclei -version is giving this as output :

[INF] Nuclei Engine Version: v3.2.7
[INF] Nuclei Config Directory: /root/.config/nuclei
[INF] Nuclei Cache Directory: /root/.cache/nuclei
[INF] PDCP Directory: /root/.pdcp

while the nuclei -ut is just showing this message and nothing else :

Your current nuclei-templates are outdated. Latest is v9.8.8
[ERR] Could not find template '/home/x/.local/nuclei-templates': no templates found in path /home/x/.local/nuclei-templates
[INF] Current nuclei version: v3.2.7 (outdated)
[INF] Current nuclei-templates version: (outdated)
[WRN] Scan results upload to cloud is disabled.
[INF] No results found. Better luck next time!
[FTL] Could not run nuclei: no templates provided for scan

The above stated output is also shown for
nuclei templates reset and nuclei -ud /.local/nuclei-templates

Expected Behavior:

After using the nuclei -update command ,the nuclei engine must update to its latest version also same thing must happen with nuclei -ut and the templates must update to their latest version

Steps To Reproduce:

make sure you have nuclei v3.2.7
run nuclei -ut or nuclei -update

Anything else:

See #2151, update option is patched in kali, so you need to install nuclei using another method like via pdtm or go install to avoid this.

i tried to do that using pdtm but still the older nuclei version is visible and the templates are also the older ones
