Setting up BubbleUPnP server on ReadyNAS OS6
I just wanted to share with you how I successfully installed ab BubbleUPnP server on my RN314:
enable ssh access
download and install Java 8 following this instructions here https://community.n...

please can one of the admins change the title FTP to BubbleUPnP... Thanks
Done.
I do want to give three general cautions on installing packages with ssh. One is that you shouldn't do an apt-get upgrade.
The second is that the NAS has a very small OS partition (4 GB) - more than enough for linux and the ReadyNAS application, but not enough for lots of packages to be added on top of that. If the OS partition fills, the NAS can become unstable, and configuration files can be damaged.
You want to be particularly careful with applications that have large databases or which do a lot of logging. One simple approach is to move the installed folders to the data volume, and replacing them with soft links.
The third is sometimes user-installed packages aren't compatible with future firmware updates.
Note that you should never trust your data to a single device (RAID isn't enough to protect it).
reagrding the first point with the apt-get upgrade: can it be reversed by OS reinstall or what would be the proper way..?
I don't know if an OS reinstall would fix it or not - hopefully mdgm-ntgr or another mod will chime in on that. Of course a factory reset would resolve it.
If you've done it and aren't seeing any issues, then I suggest leaving well enough alone.
I tried OS reinstall, but it didn't recover to the state before installing the packages.
Is there a way to make a backup copy of the OS to recover from..? I just made a factory reset and copied back the data files, and it would be nice to have also the possibility to recover the operating system on the disk with that status.
There is no supported way to back up and restore the OS. You could try to do that on your own with rsync - as long as you have a backup of your data just in case. I suggest remounting the OS partition in /mnt first (mount /dev/md0 /mnt) - there are several folders that are only used as mount points, and the /mnt approach will keep them from getting in the way. Depending on what goes wrong, you might need to restore from tech support mode, so make sure you know how to use that (and how to mount the OS partition from there).
Another suggestion is to test your package installs on a ReadyNAS VM before applying them to the real NAS.
