run apt update and get E: Failed to fetch File has unexpected size (2572288 != 2581052). Mirror sync in progress

Question

Good day!

I use local Ubuntu mirror repo to download software and security update, now when I run apt update command on a server, and it prompts the following error:

Err:12 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages File has unexpected size (2228224 != 2237636). Mirror sync in progress? [IP: xx.xxx.xx.x 80] Hashes of expected file:

• Filesize:2237636 [weak]
• SHA256:53ff6687d2d7b881a42bb252d0420483c56dda25eb31957d4b02182bba3225e5

My Ubuntu version is 18.04, I check apt sources.list setting not found any issue, do I need to wait until the repo sync finished then run apt update? or is something wrong?

Answer 1

It turns out that the mirror server run out of disk and stuck at some packages, I expand the root directory and run nohup sudo apt-mirror &, after apt-mirror sync completed, then run apt update command again, it works like a charm.
