I have a problem with creating backups from the Control Panel in a workspace installation. Both manual and scheduled backups result in the following error:
[...] System.MissingMethodException: Method not found: void ICSharpCode.SharpZipLib.Tar.TarOutputStream..ctor(System.IO.Stream,System.Text.Encoding)
at ASC.Data.Storage.ZipOperators.ZipWriteOperatorFactory.GetWriteOperator (System.String storageBasePath, System.String title, System.String tempFolder, System.Guid userId, ASC.Data.Storage.ZipOperators.IGetterWriteOperator getter) [...]
Control Panel version: 3.5.0.516
Type of installation of Workspace: deb/rpm via workspace-install.sh script
OS: Ubuntu 22.04.3 LTS (GNU/Linux 5.15.0-89-generic x86_64)
Seems to be similar to No backup on Centos in web interface but I already use a script installation.
