After update from 6.9.2 to 6.11.5, major docker and install plugins issues

[Barry Wright]

After updating from 6.9.2 to 6.11.5 my docker and plugins installs and commands have broken. 

for plugins when i try and install a plugin via the app center i get an error like below

 

plugin: installing: dynamix.file.manager.plg
Executing hook script: pre_plugin_checks
plugin: downloading: dynamix.file.manager.plg ...
plugin: dynamix.file.manager.plg download failure: Network failure
Executing hook script: post_plugin_checks

 

This occurs on any plugin i try.

The bigger issue though is my docker. existing containers run but seem abit buggy now (could be unrelated to the main issue though) however i cannot install any new docker containers or apps and when i run docker commands in unraid terminal i get errors and it is not responding.

The error is always the same
 

error: Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on 8.8.4.4:53: write udp 192.168.1.131:33262->8.8.4.4:53: write: operation not permitted

I have tried the following solutions.
 

• Restarting unraid
• Restarting docker by stopping docker using the unraid UI to turn it off and then turn it back on
• updated my /etc/resolv.conf dns values from 8.8.8.8 and 1.0.0.1 to 8.8.8.8 and 8.8.4.4 (based on a previous post from someone with similar error)
• most posts about this i find online seem to tackle this as a dns issue but the error to me indicates "write permissions" and my unraid network is working and i can even oddly updating existing running containers so this feels like my docker install on unraid is broken/misconfigured since the update
• under the tools i tried "Docker Safe New Perms" and the "new permissions" thinking "write permissions" might be by updating the permissions

 

I would rather not restore to the old unraid version as it may not fix the issue anyway and i upgraded because it stated support was/has ended for that version.

 

I am a novice at unraid and linux so if i need to provide diagnostics or other steps let me know the steps to do it.

thanks in advance for your help

Post your diagnostics

I seem to have fixed the issue (for now at least). After all of the above steps i just tried another restart of the entire server and this time it worked. im guessing one of the above steps fixed the issue but required a reboot to apply changes properly.
Will leave this for anyone else who hits this issue
