USN-5089-1: ca-certificates update

23 September 2021

A certificate about to expire was removed from ca-certificates.




The ca-certificates package contained a CA certificate that will expire on
2021-09-30 and will cause connectivity issues. This update removes the
“DST Root CA X3” CA.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 21.04
Ubuntu 20.04
Ubuntu 18.04

In general, a standard system update will make all the necessary changes.
