It's not always easy to remember what was done or never was done manually. $ cat .xsession-errors [snip] p11-kit: certificate with distrust in location for anchors: Explicitly_Distrusted_[snip].crt [snip] I restored the original state by # rm /etc/ssl/certs/* # cd /etc/ca-certificates/trust-source/anchors/ # rename -v \.crt .pem * # mv * /etc/ssl/certs/ # trust extract-compat and now there aren't p11-kit messages in $HOME/.xsession-errors anymore.
