I’ve upgraded 5 out of the 6 Percona 5.6 servers to 5.7 without /much/ trouble. In some cases the install of 5.7 failed, but a purge and re-install has always fixed it. Except for this one server we have. I’ve tried everything under the sun to get the v5.6 to v5.7 upgrade done to no avail. Since this isn’t a critical server I decided to purge 5.6 and install 5.7 directly. Even that is failing spectacularly. Here’s the relevant log portion:

2016-09-21T13:53:20.244452Z 0 [ERROR] Aborting
The last three lines are the most important parts I think. But the Warning just above the first error is confusing. I entered in a password at the prompt (and I was root, not SUDO’d) and it’s still showing an empty password. I’ve Googled the errors, but the one fix I did find for this (using mysqld_safe) didn’t work for me. This server is identical to the other servers I’ve updated (they were made from the same VM template) and yet nothing appears to be working on this one.
Any ideas?
