What’s the word on running plex server on Ubuntu 20.04? I go to download the server software and the only debs that are available are for 16.04? My current host is 16.04, but I’m planning on upgrading it not long after 20.04 comes out.
Well… it says “16.04+” which is generally read as “16.04 or newer”. Running strong on my Ubuntu 18.04 LTS.
As for 20.04 – keep in mind this is still only available as beta. Not sure I want to throw my working Plex Media Server on a beta OS during COVID19 lockdown 
If I may add?
I’m following 20.04 closely.
It’s almost at Code Freeze state.
I have the beta in a VM. It’s been rough.
I’m waiting for formal RC before testing again.
I do expect a couple iterations before the RC is fully Release Ready.

I missed the “+” on the package listing - you’re probably spot on.
And don’t worry - I have no intention of doing the upgrade until at least a week or two after the official release. 
Recommendation? Wait until 20.04.1 (First major update)
Yikes - that messy, is it?
18.04 experience: Really? I went from a rock solid 14.04 install that worked fabulous to 18.04 which stutters, the plex service freezes every once in a while and needs to be stopped/started, transcodes down to 240 and 320p on every movie, and usually struggles to add subtitles.
I have been chomping at the bit just waiting for 20.04 to come out and then, preferably for 20.04.1 tom come out just to be safe.
20.04.1 is where I would also place the as the upgrade point.
There are so many changes in 20.04 that it’s going to minimally take until the first major update to get the bulk ironed out.
Yes… updated in late April 2018 and have been happy ever after.
Maybe some hiccup during your upgrade or something odd about your setup… I’m not aware of any general issues … and I’m sure the forum would go crazy if what you describe was a common issue.

I am curious which CPU is in use and how much memory?
There was a significant change in operating characteristics and loading from 14.04 (lean and mean) to 18.04 GUI + support processes.
I suppose you’re asking @cabalist for his/her server details…
on my end it’s an Intel Core i5-7500T with 8 GB of memory
I’m sorry. Yes. @cabalist Which CPU and what amount of memory is installed ?
Yeah, 14.04 was quick and rock solid. Based on what I have seen with 18.04 I wonder where the extra required overhead is coming from It works fine, or seems to, but the only thing it does is run Plex and act as a file server to Mac clients (via smb). I just assumed that it was 18.04…I welcome any tips.
Specs:
16 GB RAM
Intel Core i5-3470 CPU @ 3.20GHz x 4
18.04.3 LTS
Fresh install with very few extraneous apps installed.
Umm, Sorry to say this but that’s about the speed of a current day NAS CPU. 4660 Passmarks.
CPU First Seen on Charts: Q2 2012
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-3470+%40+3.20GHz&id=822
It can be one HECK of a file server/ NAS and will run RAID like nobody’s business but it’s not up to this challenge. Sorry. I retired my i7-3770 for the same reason.
That explains why 14.04 runs so well on it where anything higher won’t. The threshold has been crossed.
It isn’t up to serving one stream to one device–really? That is all I am ever streaming–one audio or video stream to one device.
That’s probably ok but only H.264 1080p
I’ve been running Plex on 18.04 rock solid since it was released. As tom80H said, it must be something specific to your installation or environment.
The machine has been upgraded at least once. But previously was on i7-3770K w/ 16GB and ran fine, with few issues at all, and that was sharing to multiple endpoints in the house AND sharing across the internet between my 2 grown daughters and their families. It now runs an i7-6700K w/ 32GB RAM.
Note that I don’t use WiFi for anything in my house except mobile devices. All TVs and STBs are hardwired with gigabit ethernet.

Just dropping in to say that I upgraded to 20.04 today on my 8th gen NUC. Testing playback to various clients. So far, everything seems ok fingers crossed.

Anyone try 20.04 with a WintV QuadHD PCI-E card? I installed the Beta and Plex wouldn’t see the the card. Checked dmesg and didn’t see anything that stood out. Don’t know if it’s a Plex issue, Hauppauge issue, or Ubuntu issue…
EDIT: Fixed by adding plex user to “video” group
Upgraded to 20.04 and plex crashes on start.
