I hope that you can help. I did a search and didn't find this exact issue.
A vendor of ours recently updated their SSL certificate using a Symantec intermediate certificate. Our java process was no longer able to access the site due to PKIX path being invalid.
I ensured both packages were up to date, but this certificate is not present. I was able to update our local certificate root store manually, but would like to see if this can be updated in the apt-repo.
Thanks for your help.
