"[Errno -1] Package does not match intended download" error when installing packages from Satellite server

Resolution

• Run the following script on the Satellite server to find all packages in /var/satellite that do not have the expected checksum (md5sum or sha256sum when relevant) :

# python check-varsat.py

• After reviewing the output, delete the corrupt files

• Before running satellite-sync command, clear cache on satellite server by running following command:

# rm -fr /var/cache/rhn/satsync/*

Note : if the corruption repeats and you are using location aware updates on the satellite's rhn profile, disable it for a test to see if your problem comes from a bad mirror.

• Re-sync the channels with the satellite-sync command, to restore the correct rpms :

# satellite-sync -c CHANNEL1 -c CHANNEL2

it is also possible to use a normal full sync :

# satellite-sync

the script check-varsat.py is a simple checksum checker which is attached to this article and offers you to remove the packages which do not have their expected checksum ; it is also available on this github

Alternative method

The checksum method works - but it involves reading all the content of all rpms, which can take a long time. This other method will only base itself on the data of the rpm files :

for i in `find /var/satellite -iname "*.rpm"`
do
        rpm -vK $i 2>&1 | grep -v $i | grep -q "error" && echo "$i is corrupt"
done

to list the rpms then

for i in `find /var/satellite -iname "*.rpm"`
do
        if rpm -vK $i 2>&1 | grep -v $i | grep -q "error"

        then

             rm -f $i

             echo "deleted corrupt rpm $i"

        fi
done

to remove them. However in some scenarios if the downloaded rpm is valid but not what was expected to be downloaded, this method won't pick it.
