certutil: function failed: security library: bad database

Solution 1:

If it is new system, your certificate database might not be initialized. To fix this, perform:

mkdir -p $HOME/.pki/nssdb
certutil -d $HOME/.pki/nssdb -N

Solution 2:

In case database already has been initialised, but still is corrupted then it has to be rebuild:

$ mv ~/.pki/nssdb ~/.pki/nssdb.corrupted
$ mkdir ~/.pki/nssdb
$ chmod 700 ~/.pki/nssdb
$ certutil -d sql:$HOME/.pki/nssdb -N

Check if working alright

$ certutil -d sql:$HOME/.pki/nssdb -L
Certificate Nickname                                         Trust Attributes

Import certificate

$ certutil -d sql:$HOME/.pki/nssdb -A -t "C,," -n GoAgent -i ~/programs/goagent/local/CA.crt

Solution 3:

If you want to display certifications from a specific folder (for example, the folder which stores the cert8.db file for Firefox), you need to specify the folder with "-d":

nss-certutil -d /Users/myuser/Library/Application\ Support/Firefox/Profiles/jii912uh.default -L

Otherwise, nss-certutil may try to read *.db files from ~/.netscape folder, or maybe $HOME/.pki/nssdb as previous user mentioned.
