Hi, I am new user Ubuntu.When I am using Intel Graphics Installer, it's normal but in installing packache it's error:
Hi - those URLs you've listed from the error messages are PPAs - personal package archive.
It may be down or the owner may have retired it. They are not on by default, but you should be
able to disable or remove it from System Settings → Software & Updates → [Other Software]
If it's not listed there, you'll have to find the entries in /etc/apt/sources.list and/or
/etc/apt/sources.list.d/*.list and comment them out (a # at the start of the line will
comment them out) or remove them.
You may also choose to ignore this warning - all it means is that those particular (optional)
package repostories are currently unavailable right now.
