Server Version#: 1.20.3.3437-f1f08d65b_amd64
I’m trying to install Plex on an old Ubuntu HTPC. I recently updated it to 20.04 (it was on 14.04 before the series of updates), it has an old AMD APU and 4 GB of RAM (checking the free ram in system monitor shows about 3 GB available and during the install it stays around 1 GB in use). I’ve tried installing Plex multiple times, both with dpkg and sudo apt install and no matter what I get the same error about failed to allocate memory.

This is the exact same issue as mentioned in this thread (I’m even using ckb-next as well coincidentally), but as you can see that thread has been closed due to inactivty. It’s been over 3 months and the issue still persists, so is this something deeper/does anyone have any fixes? Do I simply have too little RAM on this machine? But then I’ve also seen docs saying Plex runs with even 2 GB of RAM. I’d greatly appreciate any help!
