Plex unable to start post upgrade: error retrieving entropy

Post by BetterNateThanLever »

Hi - running DietPi on an Odroid N2, I’ve had Plex running successfully for a couple of months. I upgraded via apt, and it Plex won’t start since.

I’ve removed the apt install and reinstalled via dietpi-software (after searching the filesystem for any remnants), but the problem persists. It’s a weird error I’m not finding anywhere related to Plex - mostly just to OpenSSL.

Any thoughts? Anyone else seen this? I’m assuming I blew up some underlying library my version of DietPi depends on when using apt to upgrade. Any thoughts on what it might be, or if that’s a red herring?

Thanks.

Hi,

maybe you can have a look to the following 2 log files. To get fresh log files, do a reboot first:

Code: Select all

cat '/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Logs/Plex Media Server.log'
cat '/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Logs/Plex Tuner Service.log'
Pls let us know if a solution is working. This could help others if they hit by similar situation. Your DietPi Team

Interesting. Looks like there's a sqlite migration just before the crash. 2ms later the entropy error pops up, unclear whether they're connected.

Unless anything else comes to mind, I guess I'll bite the bullet and re-flash the root partition.

Hi,

looks more your database crashed and tried to recover which doesn't seems to succeed

Code: Select all

Sure does. What doesn't make sense is that this happens from fresh installs. I completely remove all traces of Plex, reinstall, and this happens on initial run. I must have erased and re-installed various versions of both Plex and sqlite 10 times.

hmm maybe there is something left over even if database will be removed. But personally I wouldn't know what it could be. Do you have a spare SD card that can be used for setting up a fresh install?
