Getting some troubles with update manager.

Hello Carole,

To resolve the issue that you are getting, you will need to try the following workaround:

• You will need to try cleaning up your apt-cache, and after that you can try running any updates. The following are the commands that you will use:

sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade

• In case you still have issues after doing that, you will need to change your repo mirror.
• You will need to open "Update Manager",  and then click "Settings".
• After that you will click  "Ubuntu Software" tab, and  then select "Other.." from the "Download From".
• After that you will click the "Select Best Server" button.
• And then try updating/upgrading again.

Regards,

Carl
