Started working today and Chromium on Ubuntu suddenly throws
NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED on a well known host.
Already tried deleting .pki/nssdb/*, but nothing changed.

I have the same problem. This is what I found out so far:
https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1641380 https://bugs.chromium.org/p/chromium/issues/detail?id=664177 https://knowledge.symantec.com/support/ssl-certificates-support/index?page=content&id=ALERT2160
Are you also using Version 53.0.2785.143?
Looks like it is important when the build happened: https://chromium.googlesource.com/chromium/src/net/+/master/cert/ct_policy_enforcer.cc#44
Looks like the best workaround is to upgrade to 54.x, wait for a patch or use another browser.
Update: A new version of chromium, that fixes the problem, was just released (at least for ubuntu).

3Amazing this worked, even after I'd set the date back to the correct date.https://stackoverflow.com/users/7157744/occ could you explain why this works please? – Leo Simon Nov 14 '16 at 23:40

1This purely fixes the problem. Also it didn't last after changing the cert back. – Thomas Venturini Nov 14 '16 at 23:52

1I deleted my version of chromium using the software center and reinstalled. This appears to have fixed the problem, at least for now. The version that's currently installed is 53.0.2785.143 – Leo Simon Nov 19 '16 at 11:04
