Integrity check failed - Invalid hash .user.ini

ℹ️ Support
1

Disclaimer - I’m using the docker install from ownyourbits. I didn’t put this in the appliances category because I don’t think this is an issue with that, but I wanted to make clear that this is my environment.

A while ago I had an issue with my nextcloud instance and posted this thread. To summarize - I’m pretty sure a power outage wrecked my database, but my data is available (I invested in a UPS and will be more dilligent with backups). I haven’t heard anything in response and figured I’d make my own plan and have taken the below steps:
1: installed a fresh nextcloudplus image and updated
2: recovered from an old backup (this was from a time before several users had logged in, so their user folders were not created yet)
3: rsynced the user documents over to the new instance
4: scanned for changes from sources outside of nextcloud

Things seem to be working with the exception that I get a warning:

I’m not sure what it’s hashing, but it’s a little unsurprising to me with my recovery method that something isn’t matching there. Any way to clear this out? I’d appreciate any help.

I’m not sure how to find all the detials requested, but I can post the output of the nextcloudplus “nc-info” command (see below) and also say that I’ve installed on raspbian stretch from 4-18-2018

Alright, after doing a search for the .user.ini file to try to examine it a little I realized that it’s just in the /data/app folder, and that I ran a rsync of everything in the old version of that folder to the new one with some exclusions and inclusions as part of my process to restore the new data. Because I don’t linux much I kind of did this wrong and didn’t exclude any hidden files. If anyone ever reads this who is like me keep in mind that all linux files that start with a period (such as .users.ini) are hidden. So my guess is that even if that file has the same contents as the one that was hashed - the time stamp or some other metadata on it has changed because I copied the data from another instance of nextcloud, and that would throw the hash off.

So, the moral of the story is to rsync better! I could have just fixed this file, but for posterity’s sake (and because I’m likely to have time to kill today) I decided to start from scratch by going back to my restore file and repeating my above steps with a better rsync command that actually only moves the users’ data. Here’s what I think that would look like

rsync -avh --include={user1,user2,user3,ncp,__groupfolders} --exclude=* /media/USB/old/data/app/data /media/USB/ncdata/data/app/

however that didn’t work. In the end, given that I have so few users. I just ran an rsync command for each individual user and everything seemed to work A-OK.
