Backup not working

[Ank164]

Latest versions of onlyoffice-community and documentserverf from repo
looks like controlpanel is version 3.5.4.541
Ubuntu 18.04 when I try to run a backup in controlpanel i get the following error:

ASC.Api.ApiSetup - method error: http://127.0.0.1/api/2.0/portal/getBackupProgress.json - Server error System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: Method not found: void ICSharpCode.SharpZipLib.Tar.TarOutputStream..ctor(System.IO.Stream,System.Text.Encoding) (Fault Detail is equal to Method not found: void ICSharpCode.SharpZipLib.Tar.TarOutputStream..ctor(System.IO.Stream,System.Text.Encoding)).

Hello @Ank164 Please provide more details:

1. How did you install and update Onlyoffice Workspace?
2. What version of dotnet is installed on your server?
3. When did this error appear? Did you change any settings?

using the install-debian.sh script

sudo bash install-debian.sh -u true -it workspace

dotnet 7

appeared after upgrade

I think the problem is in the outdated version of your OS. Try updating it or migrating to a new server with a new version of Ubuntu. Be sure to backup the Data folders and the database dump.
