Maybe it's late and I'm tired, but having just arrived at this thread because I just appear to have buggered one of my two humax doing updates, I'm not sure what the actual route out is.
What I did:
I haven't updated for probably six months, so just swung by to update both. As luck would have it I tried to update the first manually, i.e. packages one by one.
jim updated fine.
OpenSSL barfed. and returned I think a 104. Anyway it also showed a small dialogue of XML which included this same text.
The next one barfed too, so I gave up and clicked back to the main EPG.
At which point I got a 500 Internal Server Error.
Tried physically powering off and on the box to reboot a couple of times, but still the same.
SMB access still works, and the remote works but the web i/f doesn't.
Figuring it was the openssl update I tried manually updating the other, just without that one. All went fine.
So it sounds sort of like what d/f was describing in is first post in the thread. it was openssl 1.1.1.b-1 that I was at.
However step by step instructions to get out of this would be nice. If they're already there I apologise, I'm just not seeing them in the discussion.
Thanks.
