@mitu said in Hash sum mismatch error:

don't have SSH enabled, then

I just enabled SSH, and updated the thread info with read-me-first topic.

I have installed the 4.4 image from the RetroPie site, and I have internet connection, I made a ping to www.google.com and work.

I now with PuTTy connected to the RetroPie.

What should do I do? Where is the path to get the log files?

Looking into it, the web

http://espejito.fder.edu.uy/raspbian/raspbian/pool/main/u/unzip/unzip_6.0-21+deb9u1_armhf.deb

isn't working, I copied that URL in my Google Chrome browser and a error file was downloaded.

But

https://espejito.fder.edu.uy/raspbian/raspbian/pool/main/u/unzip/unzip_6.0-21+deb9u1_armhf.deb

Work's just fine, so look's like

sudo apt-get upgrade

command isn't working because that http isn't https.

EDIT:

I have changed the /etc/apt/source.list

and added

deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi firmware deb http://archive.raspberrypi.org/debian/ stretch main ui

it seems it working now, the upgrade is doing downloading files without error.

But, is ok to use those repositories?

My guess? Is a problem for South American people (I'm from Argentina), that the source list is unupdated or wrong setted, because when I got the url it use http and not https, looks like that's the main reason.

I tried to install the retropie-manager (after the update & upgrade) and I got this error

Could not install packages(s): python-dev virtualenv.

EDIT 2:

I have it working, to workaround I just change /etc/apt/source.list.p/retropie.list (or something like that)

and added (can't edit because the Akinet detect that is a spam, but add deb before the url)

https://espejito.fder.edu.uy/raspbian/raspbian stretch main

After saving the file, I use sudo apt-get clean and sudo apt-get update and everything is working just fine (or it seem's like that).

The error is that the URL is unupdated, but isn't the best option.

Idk if I have to send an email to the RetroPie developers to update the repo url for Argentina.

Remove the raspbian.raspberrypi.org repository from the list of repositories in the /etc/apt/sources.list.d/raspi.list file and re-try.
