That would be really nice because any package build that requires mono and needs nuget packages needs to run the cert-sync in its build steps or else it fails.

A somewhat related issue with Mono 5.0 is broken https support. Mono 4.8 moved to TLS1.2 provided by Google's BoringSSL project, however, https support is broken in Mono5.0. The work around is " export MONO_TLS_PROVIDER=legacy" instead of btls. Any chance of setting the default to legacy instead of btls in Solus builds? This will allegedly be fixed in Mono 5.1

I just remembered that we now have a tool called usysconf that would integrate and eat this task for breakfast, running

sudo cert-sync /etc/ssl/certs/ca-certificates.crt and creating (/usr/share/.mono) when /usr/bin/cert-sync exists and the certs change. Maybe I'll even try getting my C on xD

I see that this issue is closed but I just ran into it today.

We've got this API test framework that uses RestSharp and authenticates using rest endpoints. Needless to say it's required to have working certificates and things before these endpoints behave properly. Interestingly, I had the same issue on openSUSE and it was resolved by using the cert-sync command.

I was able to work around this issue on Solus by using that cert-sync command has folks have posted above but I'm curious why this isn't run as a post-install task automatically? The mono-docs explicitly state that:

Note that a default installation of Mono doesn’t trust anyone!

This means that any Mono install without initially running cert-sync is ostensibly broken.

Can't reproduce:

Certificates populated

$ ls /usr/share/.mono/
certs  new-certs

If you do something odd like remove /usr/share/.mono then it won't necessarily regenerate them on reinstall

In my case, certificates are not populated as in @sunnyflunk's message:

Am I missing something?
