Electron-builder: Electron-Updater differential update fails with operation overlaps previous operation

[yhaering]

• electron-builder: Version 20.36.2
• electron-updater: Version 4.0.4
• Target: nsis-web
• System: Windows

The AutoUpdater gives me this error...
[2018-11-18 17:01:42.356] [error] Cannot download differentially, fallback to full download: Error: operation (block index: 23902, checksum: Vx/fVEzWD3gMPbOsQJC+QZlJ, kind: COPY) overlaps previous operation (checksum: Vx/fVEzWD3gMPbOsQJC+QZlJ): abs: 7267809 until 500356092 and 500206446 until 500238540

... using this configuration

"build": {
    "appId": "<appId>",
    "nsisWeb": {
      "oneClick": true,
      "perMachine": false,
      "differentialPackage": true
    },
    "publish": {
      "provider": "generic",
      "url": "https://<username>:<password>@<URL>"
    },
    "win": {
      "icon": "./lib/resources/icons/icon.ico",
      "target": "nsis-web"
    },
    "files": [
      "*.js",
      "build/**/*",
      "node_modules/**/*"
    ]
  },

The connection to the server seems to work as the updater can find the new version and successfully falls back to the full download. The _package.7z_ exists in the {User}/AppData/Local/{name}-updater.

Thanks in advance.

Also got this error with nsis target

[develar]

Please provide links to old and new executables and blockmaps.

[develar]

Just to make clear — update is working, but instead delta-, full- download is performed.

[sandeep1995]

Facing exactly the same issue for nsis target. I also enabled my generic server to accept byte ranges.

[sandeep1995]

Also got this error with nsis target
@alxmiron Are you able to solve? @develar Is there any way out?

[alxmiron]

No. I just get full download each time instead of differential

[sandeep1995]

Yeah, I am also facing the same. I want diff download. Any luck on these? @alxmiron @retina-design

[zhaoterryy]

Please try using 20.34.0 for now.

[sandeep1995]

Please try using 20.34.0 for now.

@zhaoterryy Downgraded to 20.34.0 Still facing the same error. I am building for only nsis.
I am using minio server as a local s3 setup.

Here is the log

[zhaoterryy]

Downgrade electron-updater as well, to 3.2.3.

Just an FYI: Electron-updater and electron-builder versions are tied together, they need to be kept in sync. Check release logs in https://github.com/electron-userland/electron-builder/releases for electron-updater versions.

[develar]

And no one still answered me... "Please provide links to old and new executables and blockmaps." Now I have time to investigate issue, but I don't have test data....

[sandeep1995]

@develar I would like to really help you out in this regard. But as our repository is closed source, I can't share the links.

Is there any other way to provide you the same?

[develar]

Validation disabled for now, because assert message is clear that probably validation is too strict. Please try electron-updater 4.0.5.

@zhaoterryy Thanks for sorting issues out — participation of such VIP users like you, increase issue priority, nearly as donation :)

Is there any other way to provide you the same?

@sandeep1995 Is it possible to provide old and new blockmap files? These files contain only blake2 hashes and sizes.

[LurknOctopus]

Was facing the same error for a while and finally found the right combination for my app! Hope this helps anyone still searching:

electron: 4.0.6
electron-updater: 3.2.3
electron-builder: 20.34.0

[gimdongwoo]

Please reopen this issue.

[liflovs]

Still a problem
"electron-builder": "^21.2.0",
"electron-updater": "^4.1.2",

[8balloon]

Thank you @LurkingOctopus for your answer.

If anyone doesn't want to update electron itself, matching up the following dep versions may be sufficient:

electron-updater: 3.2.3
electron-builder: 20.34.0

(This worked for me)

[doylemark]
