Authenticity of wordpress update could not be verified as no signature was found

now that php 7.2 and beyond doesnt use mcrypt, it is suggested that for those with Wordpress websites on their servers, one should install libsodium.

I have done this however, in Wordpress on my server, I am still getting the following error whever i try to run any wordpress updates…

Update WordPress

Downloading update from…

The authenticity of could not be verified as no signature was found.

Unpacking the update…

Could not create directory.

Installation failed.

I am also seeing the following in the virtual server apache error log

ModSecurity: Warning. Operator GE matched 4 at TX:outbound_anomaly_score. [file “/usr/share/modsecurity-crs/rules/RESPONSE-980-CORRELATION.conf”] [line “82”] [id “980140”] [msg “Outbound Anomaly Score Exceeded (score 4): PHP Information Leakage”] [tag “event-correlation”]

I am also seeing the following error from Wordpress whenever i try to install plugins…

Installation failed: Could not create directory.
