List of Root and Intermediate certificates

Question
Where to find the root and intermediate certificates for Comodo (Sectigo) certificates?
Answer
SSL installation requires root and intermediate certificates forming a "chain of trust".
If at least one component is missed chain will be marked as non-trusted by some browsers.
Please, find the updated list of all the CA intermediate and root here.
"Comodo" renamed into "Sectigo" since 01-11-18.
Since 14-01-19 major part of Comodo products changed root certificates.
Products active after 14-01-19 use new root during activation and reissue.
Products active before 14-01-18 using old "Comodo" root for activation and use the same for reissue.
Actual for certificates issued before 14.01.19 and actual for their further reissues.
