Hello,

It looks like there is an issue with ppg-12 apt repository

```auto
Err:1 http://repo.percona.com/ppg-12/apt jammy/main amd64 python3-ydiff all 1:1.2-1.jammy
  File has unexpected size (22074 != 22090). Mirror sync in progress? [IP: 10.1.1.20 3128]
  Hashes of expected file:

```

there is indeed a mismatch between the file

```auto
curl -LO http://repo.percona.com/ppg-12/apt/pool/main/y/ydiff/python3-ydiff_1.2-1.jammy_all.deb
  % Total % Received % Xferd Average Speed Time Time Time Current
                                 Dload Upload Total Spent Left Speed
100 22074 100 22074 0 0 8199k 0 --:--:-- --:--:-- --:--:-- 10.5M

```

And the size in `Packages`

```auto
Filename: pool/main/y/ydiff/python3-ydiff_1.2-1.jammy_all.deb
Size: 22090

```

The last update was `2024-Sep-13 07:33`, there probably was a problem during the update ?

Thanks !

Hi @b.ogier  
Could you please retry installing `python3-ydiff` once again after running `apt update` command there is a possibility that you were trying to install the package at a time when the repo was in the process of update.  
Fro our end we don’t see such an issue now:

Hi Alex,

My apologies, the issue was due to a (misconfigured) proxy cache that was in the way. Clearing the squid cache resolves the issue.

Sorry for the noise and thanks a lot for your time !

KR,
