I installed the pyrmont package a few days ago and it was attesting no problem. When it stopped missing attestations, I check the dappstore for an update and I see there is no entry for Pyrmont. Then at the bottom of the dappstore, I see there is a button that says “Show packages still propagating”. When I click there, I see several packages that say below their name “Failed to download package from IPFS”, including Pyrmont.
Edit: I remembered that I turned on my router firewall recently. So I went to router settings and forwarded the IPFS ports to my dappnode address. I think this may have fixed it. I now have access to Pyrmont and Geth package updates.
