Public bug reported: On 6 October2020 on an Ubuntu 16 system with kernel 4.4.0-187-generic, by "unattended-updates", python3-urllib3 1.13.1-2ubuntu016.04.3 is updates to python3-urllib3 1.13.1-2ubuntu016.04.4
After this update Samba doesn't work any more. Registering of the Samba server at the Domain Controller no longer works. # net ads join -U admsamba Enter admsamba's password: Failed to join domain: failed to lookup DC info for domain 'SAMBA-DOMEIN.LOCAL' over rpc: Undetermined error >From the website below I downloaded the former version python3-urllib3 >1.13.1-2ubuntu016.04.3' https://Launchpad.net/ubuntu/xenial/...ython3-urllib3 With dpkg I installed the former/correct version 3 over the new/wrong version 4. #dpkg -i python3-urllib3_1.13.1-2ubuntu016.04.3_all.deb dpkg: warning: downgrading python3-urllib3 from 1.13-1-2ubuntu0.16.04.4 to 1.13.1-2ubuntu016.04.3 (Reading database ... 168370 files and directories currently installed.)
