I am running on 2.0.6.3\_beta Ubuntu 22.04. When I action an upgrade (to 2,1,02) it fails with the following error message  
"System.Exception: Unable to verify unpacked folder for url: [https://alt.updates.duplicati.com/beta/duplicati-2.0.8.1\_beta\_2024-05-07.zip](https://alt.updates.duplicati.com/beta/duplicati-2.0.8.1_beta_2024-05-07.zip)

or…

"System.Exception: The found version was not the expected version  
at Duplicati.Library.AutoUpdater.UpdaterManager.VerifyUnpackedFolder (System.String folder, Duplicati.Library.AutoUpdater.UpdateInfo version) [0x0011c] in \<8d4cb1693e00483189d3952c3f0ed20f\>:0 "

Please advise what I should do

Thanks

Hi @Norman_Bearon, welcome to the forum 👋

That is a bug in the update system when going from anything older than 2.0.8.1 to 2.1+.  
You need to manually uninstall Duplicati 2.0.6.3 and then install 2.1.0.5:

For now, we do not have automatic updates.

Also, note that 2.1 was a major change, no longer relying on Mono, and adding a mandatory access password:
