Can't get ASPNET Core Developer Certificate to work Ubuntu 22

[AlanGRutter]

I have run your scripts for Ubuntu and everything seemed to work fine except an error about ca-certficates.crt containing more than one cert.

I have looked at the 'Linux Certificate Not Trusted' section on this page and also this issue.

I have verified that the fingerprint of .dotnet pfx file is same as the dotnet-devcert.crt fingerprint, however when I run my application in VSCode it still gives me the error 'The ASP.NET Core developer certificate is not trusted.'

Tried everything - totally stumped as to how to get this to work. Any suggestions, thoughts or ideas?

I also noticed that the provided solution doesn't work for the current version of Ubuntu :/

Not working on Ubuntu 25 either. Seems abandoned :(
