Dockers not updating but available

[JamesBondPPK]

Hi, 

 

I am having trouble updating my dockers. My server seems to be able to check and find updates, which then adds the "apply update" next to the dockers. However, when I click "apply update" or click it in the drop down menu (right-click -> update), the dialogue box pops up and it just closes, then reopens the docker and nothing changes.

 

An added note and I think this is the issue, but I still don't know how to fix it, but when I try to install another app, it pulls no data (dialogue box) and fails to download anything. 

 

I can't remember the last time this worked, but it may have been in 6.8.x, and I'm running 6.9.2. DNS is set to router, all dockers and VMs access the internet.

 

Anyone know how to fix this?

Post your diagnostics

I figured that was needed, here they are! And thank you!tower-diagnostics-20211113-1051

Try setting static DNS addresses in Settings - Network (208.67.222.222 / 208.67.220.220)  Won't hurt.

If I set it to that, with on "static" instead of "automatic" it say "match requested format." Can I leave it on automatic? Sorry, I don't understand the Network stuff too well...

You didn't type it in correctly.  2 separate entries (one on each line)

208.67.222.222

208.67.220.220

Yeah I did that. That was the first thing I checked. Found the error, I copied and pasted the original IP address, and the second number is 267 instead of 67. The 67 worked.

That seemed to fix the dockers not updating, or at least it appears so. And it fixed not being able to download apps. Everything is working again! Thank you!!!

 

So what are the DNS IP address to?

A DNS server is what translates something like http://google.com to instead be http://142.251.32.78 which is how the entire internet works.

 

By not specifying a DNS server, the system defaulting to using whatever DNS addresses are set in your router (or modem) which are usually handled by your ISP.  Most ISP's DNS servers are terrible and don't resolve correctly all the time.

 

Those 2 addresses are for the OpenDNS servers.  There are many available via a google search.  EG: If you would like Google to know and use in their analytics that you've installed an app from docker or a plugin from GitHub you would use instead 8.8.8.8 / 8.8.4.4 (Google's servers - Incredibly awesome, always resolve, but they do track you)
