I'm trying to upgrade Umbraco from 8.5.5 to 8.10.1, but when I try and boot the site, I can't get to the installation Wizare I get the following error:
Any ideas?

Would also do it in smaller steps, had also a lot of issues going to 8.9.1 deleting the temp directory and on all main root nodes do a Publish with Descendants fixed things for me. Haven't updated to 8.10.x yet but not sure if much is added after 8.9.1.
Also when upgrading failed and you downgrade via nuget, als make sure you also reset the version number in web.config.
This error can also occur if the application do not have access to the database. So do also check your connection string and that the user is added and have access to the database.
I had the same issue recently and it turns out that in my zeal for keeping the DB streamlined, I accidentally deleted the data from the [umbracoLock] table. These are the default values required:
I had the same issue now in umbraco 13 and it was solved by assigning full control permissions to IIS_IUSRS user on the hosting folder. Umbraco CMS requires access to delete, create, modify, and execute.

I feel like im stuck on 8.5.5 for ever... what ever I do I can't get this upgrade to work.
Hey, I came across this issue yesterday, removing this from my web.config fixed it for me :) I then re-added it after the upgrade was complete
I actually tried that... still didn't work for me. What versions are you working with?
I jumped from 8.4.2 to 8.10.1, this is the only change I had to make though :/ are you upgrading via nuget?
It's worth noting that I tried jumping in smaller upgrade steps too, i jumped to 8.6.4 first, without that flag in the web.config
Going from 8.5.5 to 8.13, this was also the solution for me.
Thanks!
Would also do it in smaller steps, had also a lot of issues going to 8.9.1 deleting the temp directory and on all main root nodes do a Publish with Descendants fixed things for me. Haven't updated to 8.10.x yet but not sure if much is added after 8.9.1.

I had the same issue recently and it turns out that in my zeal for keeping the DB streamlined, I accidentally deleted the data from the
[umbracoLock]table. These are the default values required:This was admittedly a v9 project I was working on but the data is the same in a v8 project so I imagine that it would cause the same issue.
I had the same issue now in umbraco 13 and it was solved by assigning full control permissions to IIS_IUSRS user on the hosting folder. Umbraco CMS requires access to delete, create, modify, and execute.
is working on a reply...
