Bolt Python Library Setup error

On running the command “sudo apt-get -y update”, it executes the command but at the end it says “Some index files failed to download. They have been ignored, or old ones used instead.”

After executing the next command “sudo apt install python3-pip”, it says “0 upgraded, 0 newly installed, 0 to remove and 8 not upgraded”

Also, the command “sudo pip3 install boltiot” gives the following error

Please help me solve these bugs as soon as possible. I tried looking at similar topics, it didn’t really help sadly.
