I tried to install updates from the update manager but it always displays an error message Failed to download package file and the details is:
Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/h/hplip/hplip-data_3.10.6-1ubuntu10.2_all.deb The HTTP server sent an invalid Content-Range header [IP: 91.189.92.167 80]
Please can someone help me out.
Thanks for your response...
