I use the os-speedtest-community plugin from mimugmail repository. I am setting up a new firewall with v26.7, and I cannot find it in the plugins list. It's alive and working on my older firewall that I upgraded to v26.7 with speedtest already installed. Thoughts?
Did you click on "show community plugins"?
Having read about possible incompatibilities of third-party-plugins I removed os-speedtest-community plugin before updating to avoid any troubles with remote updates.
Immediately after the update no community plugins showed up at all even after removing and adding again the repository. Now 4 days later I do see most of mimugmail's (the only repository I use) plugins but speedtest (the only non-OPNsense plugin I use) is still missing. I'd guess it'll be just a matter of time till it shows up again within the repo.
Try opening an issue on the Mimugmail GitHub: https://github.com/mimugmail/opn-repo/issues (https://github.com/mimugmail/opn-repo/issues)
