I installed i2p from FreedomBox but was linked to the Ubuntu focal repository for the program. Now, I suspect that the removal of i2p from FreedomBox did some unconfiguration of my running i2p.
I could use the FreedomBox firewall configuration details for starters, I’m not sure if there will be additional things to fix up after this. My i2p connection and proxy are running, but I can’t get to the console, for example.
