Now, the synchronization has stopped, and I get a warning \"The server version 8.1.9.2 is unsupported! Proceed at your own risk.\" I understand that I should urgently update the server -- however, I'm in a position where I can currently not do that. The message does also not detail the potential risk of proceeding with the new client (loss of all data possible?). Therefore, this is also not a realistic option.\r\n\r\n### Expected behaviour\r\nAn automatic update shall not bring down a running ecosystem. I see the following options, in order of preferrence:\r\n1. The automatic update process shall check if the update breaks the compatibility with an active account/server. If that is the case, the user shall get a warning that the update would break the compatibility *before* the update happens. They shall have the option to cancel and postpone the update.\r\n2. There shall be an easy way to revert to the last client version before the automatic update in case of incompatibilities. One option would be to keep also the *second most recent* install file in %HOMEPATH%\\AppData\\Roaming\\ownCloud. Currently, only the *most recent* install file is kept there.\r\n3. At least, it shall be possible to manually find a recent binary version of the client to install it. However, the most recent version of the client I could find at https://owncloud.org/download/older-versions/ is Version 2.3.4 from 2017-11-03, i.e., 11 months old. This is definitively much older than the version before the most recent automatic update, as I remember automatic updates during the last months. (Can anyone point me to more recent versions online? Thanks!)\r\n\r\n### Steps to reproduce\r\nNo active steps necessary, if auto-update is activated.\r\n\r\n### Server configuration\r\nOperating system: Ubuntu 14.04.5 LTS\r\n\r\nWeb server: Apache 2.4.7\r\n\r\nDatabase: mysql\r\n\r\nPHP version: 5.5.9\r\n\r\nownCloud version: 8.1.9.2\r\n\r\nStorage backend (external storage): ?\r\n\r\n### Client configuration\r\nClient version: 2.5.0 (build 10560)\r\n\r\nOperating system: Windows 10 Pro\r\n\r\nOS language: German\r\n\r\nQt version used by client package (Linux only, see also Settings dialog): n/a\r\n\r\nClient package (From ownCloud or distro) (Linux only): n/a\r\n\r\nInstallation path of client: C:\\Program Files (x86)\\ownCloud\r\n\r\n### Logs\r\n\r\nI'm not aware of logs regarding this problem. I could not find a log of the automatic update giving the version of the previously installed client."}}
