I was actually very interested on this use case as I even saw it on Reddit, but never got to try it on uRaid. Would you mind telling me if the binary works there? Thanks! |
✅ I can confirm the binary you posted above does work on ❌ The Using the below commands and eventually saving them as a user script (running at first start of the array) made mosh working like charm wget -O /usr/bin/mosh-server https://github.com/blinksh/mosh-static-multiarch/releases/latest/download/mosh-server-1.4.0-linux-amd64

Hi, |
We are working on a fix for this that should be out soon, but in the meantime you can install on your own in the server by just doing what @verypacific suggested: |

Fixed. Will be out on 17.2.2 |

Use mosh1 for the deprecated (previous) mosh version. |

@verypacific thanks for taking a look at this so quickly. I think I may have made a rookie mistake and forgot to delete the "invalid" binaries you may already have in .blink folder. Would you mind doing so? The flow is to download the binary if there is none (but in your case there is, although invalid) and do a checksum. Then we upload the binary to the server. But if you already have a file there, we skip the checksum and upload directly. I did it that way so people could also "automatically upload" binaries they may have from their side. |

Same here; after the "Mosh server not found" dialog and the download attempt, |

Hi @carloscabanero I was thinking the same too so I completely removed the The log I posted above for unraid already shows the process of a fresh download with no file present. The upload progress bar is practically not present as the small pop-up notification is only shown for a split of a second (whereas on Ubuntu an actual upload to the server is happening) Unfortunately it still results in the |

Apologies for the delay getting back on this @verypacific & @mpepping. We have 17.3.0 coming up and it is taking most of the time. I fixed the issue of an erroneous download being kept in the file system, but unfortunately, I haven't been able to reproduce your issue. I have tried many different distros (Ubuntu, Fedora, etc...), and they are all working fine. The flow is really easy, but the thing is that except for the original message that has already been fixed, I don't see now from the logs what is the new location Blink is trying to download from that is causing the "Not Found" error message. Can you send me the specific new line: Also, it cannot happen that on the same run Blink downloads a file with "Not Found" and uploads that trash to the server. We perform a checksum validation and that would have failed. On a subsequent run though it would be uploaded - and that's what your logs show -, and is what I realized we were not doing properly and should be fixed for 17.3.0. |
Hmm, the line is:
Blink v17.2.2.868 |
