Comment 23 for bug 1771880

I have installed VirtualBox on my Mac laptop, and built Ubuntu 19.04 guest VM - but had issues with everything that requires HTTP/HTTPS access. Eventually, I came across this post - which matches the issue I have and explains why that's so...

To have another look at it, I searched for other ways (other than using SSL import utility) - and came across 'pk12util' which "supposed to" be able to import PK12 certificates (under normal circumstances). Using this utility, I'm getting "SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format" errors:

vpogrebi@vpogrebi-VirtualBox:/usr/local/share/ca-certificates$ sudo pk12util -i cacert.pem
pk12util: function failed: SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format.
vpogrebi@vpogrebi-VirtualBox:/usr/local/share/ca-certificates$ sudo pk12util -i IDEXX-NewPKI-SHA2-Chain.crt
pk12util: function failed: SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format.
vpogrebi@vpogrebi-VirtualBox:/usr/local/share/ca-certificates$ sudo pk12util -i dockercom.crt
pk12util: function failed: SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format.

Hope this can help resolving the issue; but in the meantime - it seems that I have to completely delete Ubuntu 18.04 VM and start all over using older (16.04 ?) version.
