Hi folks, been having this problem for a while now.  Dockers indicate an update is available but when I try to install the update it downloads 0 bytes. This happens on with all dockers.  If I reboot the server then everything seems to work fine for a month of so but I'm not a fan of un-necessary restarts.  Any idea what might be causing this?

All lsio containers will signal an update every Friday @23:00 GMT, whether or not there is an actual update for the container available or not (ie: no update in the base OS or container)

Thanks.  All the containers showing an available update are Lsio.  Should they change to 'green' after attempting the update if no new images are available?  These are staying 'blue'.

Never even looked at the dashboard.  I go by whatever the docker page says.

As an update, it has been several more weeks and still unable to update any docker that is showing available updates.  docker.log showing connection errors whenever it's trying to pull images.  Below are 3 attempts, 2 for LSIO and one for Binhex containers.

Same kind of issue happening for me. Haven't messed with DNS at all, but I can't even ping docker.io. Every other URL pings just fine, but none of the Docker addresses will return packets. Haven't been able to update Docker containers since 6.5.2 update.

Earlier this year I had installed Pi Hole as a DNS server.  Even though the dockers had updated after that, I am wondering if something in my DNS settings are at fault.  Plugins are updating just fine though.

 

Other than the timeout errors in the docker log I don't know what log would give more detailed info on why it is timing out.

You can always remove pihole change your config accordingly and see what happens.

I had previously tried disabling Pihole and assigning other DNS servers through my router with the same results. 

 

As per your suggestion, I removed it entirely, removed all manual DNS settings from my router so it pulled the DNS IPs from my ISP, and reset unRaid network settings to default/automatic as well as enabling ipv6, which was disabled.  Dockers from multiple sources started pulling down new images without issues.

 

Tried to re-install Pihole, leaving unRaid network settings at default which is using my routers ip as DNS server.  Pointing the router to Pihole had the problem return.  Tried various configurations and once I changed the DNS servers I had specified in Pihole to the Google servers, instead of the ones I was trying to use, then Dockers could update again.

 

I can't say for sure if it was the DNS servers I had picked but everything is working as it should now.  Thank you for the fresh perspective on the problem.
