I've recently installed Pinta, a program for drawing and image editing, and as part of the installation it installed 173 root certificates (see below).

Is it normal practice to do so? Why does it need these certificates for? Also how to know if these certificates are safe?

The messages you see are part of the installation of ca-certificates-mono which is required by mono (.NET runtime for Linux) which is required for your program.

ca-certificates-mono actually doesn't install new certificates! What it does is to add your existing certificates to the mono keystore! Mono doesn't use the system certificate store (a bunch of files in some folder like /etc/ssl/certs/) but has its own binary certificate store. To allow programs using mono to verify TLS connections, mono needs the root certificates in there. Because installing new certificates selected by mono developers could be a security risk, they don't ship CA root certificates with mono. Instead, they import all the certificates you (or the vendor of your distribution) already trust into the mono trust store.

So nothing to worry about. What you should keep in mind is, that if you change the certificates you trust, you have to update the mono trust store too to reflect that changes.

In general: While in this case apt-get didn't install the certificates, all the certificates you have are most likely installed with the package ca-certificates. All packages installed with apt-get are signed by your distributor (debian, ubuntu,...) or someone else whom you explicitly trust (if you add some key with apt-key). If you don't trust them, you probably shouldn't install software provided by them. If you should trust any CA is a different question...

  • Insightful. The same applies to ca-certificates-java package, which is required by openjdk-8-jre, to give an example. – Simón Jan 30 '17 at 4:35
