Certificate error when upgrading to Oneric

Posted on Fri 30 December 2011 in Sysadmin

Just updated one of my Ubuntu servers to Oneric, and I noticed some error messages during the installation:

error adding /etc/ssl/certs/brasil.gov.br.pem
error adding /etc/ssl/certs/cacert.org.pem
error adding /etc/ssl/certs/ca.pem
...

I found a solution in this forum post:

$ sudo dpkg-reconfigure ca-certificates

…and select all certificates in the dialog.

(To be honest, I don’t know if the error actually caused any problem for me, but it’s nice to have preempted any problems now that I have the error messages fresh in mind.)
