Dump MySQL rdbms … mysqldump: Error 2020: Got packet bigger than ‘max_allowed_packet’ bytes when dumping table ‘article_plain’ at row: 8704 … failed
The shadow.service unit reported that it had failed and threw the following error message: “user ‘colord’: directory ‘/var/lib/colord’ does not exist”. I had no recollection of housing such a user, but by issuing the command below there was hard proof (image to the right) that colord was indeed a homeless user on my system, and her home was supposed to have been /var/lib/colord.
A while back I did some consulting work for a small ISP who had received complaints from a few customers that believed they could not use the ISP’s SMTP server to send email to outlook.com or hotmail.com accounts. These customers claimed they never got any bounce message (Non-Delivery Report) in return, so they firmly believed the problem resided with the ISP.
