Hi, In the last days we started suddenly having an issue with sending emails… then we’ve tried to upgrade/update without success (the update page hangs and every component - docker, discourse, plugins - get stuck at “Checking for new version…”) and then we tried to update everything via root but th…

I’m just posting to update on the situation. It got solved with help from ChatGPT. After trying different solutions, this part showed that something was wrong with the permissions or security policies: Try Running a Container with the --privileged Flag This bypasses some restrictions that might…

Are you operating in a special territory such as mainland China? I would check DNS on your host and then check DNS in your docker. check DNS on your host: resolvectl status|egrep Servers nslookup github.com check DNS in your docker docker exec -it app bash -c "cat /etc/resolv.conf" docker exec …

Ok, so: on host DNS: #resolvectl status|egrep Servers DNS Servers: 8.8.8.8 Fallback DNS Servers: 8.8.8.8 DNS Servers: 8.8.8.8 8.8.4.4 #nslookup github.com Server: 8.8.8.8 Address: 8.8.8.8#53 Non-authoritative answer: Name: github.com Address: 140.82.112.3 On Docker DNS: #docker exec -it app …

It’s a standard install that have been working very well so far in AlmaLinux in the past few months (and before that well too in CentOS). How can I update the docker installation (without the usual rebuild instruction with launcher or the through the website as none of these methods seem to be work…

Before you go any further, please take a backup (if you can) and download a local copy. (Perhaps try Move a Discourse site to another VPS with rsync ) Please try these, they might give a hint: docker --version docker run hello-world

With a bit of help from ChatGPT I found that it is the Docker’s Bridge network configuration or whatever that means that is the problem. I’ve tried several fixes but so far without success. Haven’t tried this one yet: [The image provides steps to manually reset Docker networking by stopping Docke…

I’m afraid I don’t know. I trust you have a safe recent backup. The least disruptive thing to do might be a reboot.
