I have a headless Plex Media Server running on and old core2duo machine with Peppermint Linux (v3?) which has served me well for a good few years. At the time I installed it I used the version of Plex Media Server available from the Software Manger application supplied with the OS. I imagine this means the software was installed from a repository and, from what I've read online, this is no longer maintained with newer versions of code.
I have recently received an email advising me to upgrade because the version in question (0.9.9.7) contains a vulnerability. Even though I don't access the server from the outside world, it makes sense to consider upgrading anyway.
However, because of the method I used to install the system in the first place I don't know if downloading and running the latest .deb package from the Plex site is going to come back to bite me if, for example, the installation directory used by the Peppermint Linux Software Manager application is different to the one used when installing manually and I'm left with either a completely broken Plex installation or two separate installations trying to compete with each other.
Ideally as I've obviously watched a whole load of content during this time and have also edited some of the entries to ensure the correct artwork is downloaded I would like to in a position where, once upgraded, all this information is preserved.
I am relatively comfortable with Linux, but am by no means an expert, so would be grateful if anyone could come up with an upgrade plan (with commands for me to follow) so that I can go about performing the upgrade.
Many thanks to the community in advance.
Phil.
