Server Version#: 1.0.3 Player Version#: \ Hi all and hi @ChuckPa I am reasonably confident Linux admin. But am stuck migrating Plex from Mac to Linux. I have followed the official guide to move PlexMS App Dir to a new system - in my case from a very old but perfectly functioning MacOS Catalina install (with uptodate PMS) to an Ubuntu LXC. The actual media remains on a NAS. I have copied the Application Data folder over using rsync. I have opted to leave out the uploaded media folder as this was 90GB. I have chowned the folder and contents to plex:plex I have updated the Preferences.xml file with the identifiers from the Mac Install. (I note that this file is very brief compared to the mac PLIST/defaults output, but still, I copied over the identifiers) After seeing db errors starting plex, I followed [another forum post](https://forums.unraid.net/topic/124023-plex-unable-to-set-up-server-sqlite3_statement_backendprepare-database-disk-image-is-malformed/) that suggested eliminating all db files except ```auto com.plexapp.plugins.library.blobs.db com.plexapp.plugins.library.db ``` I tried ChuckPa’s automatic DBrepair script (cool!) - and restarted plex - no dice, same error as below: The systemctrl/journalctl output I get is: ```auto Jul 29 10:00:34 plex systemd[1]: Starting Plex Media Server...

Jul 29 10:00:51 plex systemd[1]: Failed to start Plex Media Server. ``` I have removed the old folder and let plex start fresh again, and repeated the process - obviously I could just clean slate it, but after 10 years at least of being a lifetime subscriber and accruing a lot of library metadata and shared access, I do not wish to let this go lightly. Really appreciate it if anyone can help - @ChuckPa , I have seen your replies to others migrating to look for you other posts, but honestly I have not been able to find one that is relevant or surpasses what I have already read and tried. ---

> [@hutchwilco](#): > > `attempt to write a readonly da` Plex cannot write to the database. Verify permissions for the [Plex Data Folder](https://support.plex.tv/articles/202915258-where-is-the-plex-media-server-data-directory-located/). See Linux Tips: [Migration from another OS to Linux](https://forums.plex.tv/t/linux-tips/276247/23). Specifically (adjusting if needed for running in an LXC): - Change the ownership of the files to the Plex user on the Linux host. ```auto # chown -R plex:plex "/var/lib/plexmediaserver" ``` - Make certain Linux file permissions are set correctly ```auto # find /var/lib/plexmediaserver -type d -exec chmod 755 {} \; # find /var/lib/plexmediaserver -type f -exec chmod 644 {} \; ``` ---
