Hello Jeremy!  Long time no talk to.  Hope you're doing well.  Myself, I've been up to my neck in alligators for as long as I can remember now.  :0 

I just tried to install v18 of Redmine because I can't get my reports to work like I want them to on my old version. (That's been an ongoing issue for years, not a TKL issue.)  So I thought I'd install a fresh VM, screw around with some test data and modifying the .rb files or whatnot to see if I could get my reports like I wanted, and then I'd migrate my data to the new system.  I'm having a hard time getting v18 to work however, as it looks like MariaDB is refusing to start.  I install like I've always done and everything appears to work, but RM won't come up.  The only thing I could find based on the error msgs was the possibility of ib_logfile0 not being there after Maria not being shut down properly and then upgrading to a new version, but with a fresh install not sure that's applicable. 

Anyway, just thought I'd check to see if anyone else had seen this problem before I continue to beat my head against the wall.  I've installed this as a VM on Proxmox 8.1.4 with 8GB RAM and a 100GB storage space.  All the settings are pretty generic like I always do and I just installed a clean RM v17.1 VM to make sure I hadn't changed something that the previous version didn't like.  My old version 17.1 is running fine and the new VM came up with the fresh install and is running fine, so I'm not sure what I'm doing wrong with 18.0.  Anybody have any idea, give me a holler! :)
