Install Updates could not successfully download and install available updates.

You will need to wait for one of the LL staff or developers to assist you.
Removing them would not be good it says, it doesn't remove them as you have not typed the command it tells you to type.I won't add the command below as it may be potentially harmful it says to use this, at this time.

Try now (for no installation candidate)

Code:

sudo apt-get update

So that the APT database knows the software sources.
After this you may need to do

Code:

sudo apt-get upgrade

Most of these (if not all) are to do with Python3 not being configured.

That's a hell of a mess you have there. A 10 minute reinstall of the OS is a much more efficient use of time in this instance. Then go through and read the Help Manual for a clear overview of how to use LL. Cheers

[member=2]Jerry[/member] is this the bug from HPLIP updates and Python3 ?

[valtam]

[member=411]bitsnpcs[/member] unsure. Which bug? Do you have link?

[bitsnpcs]

I just noticed it from [member=6978]atpersian[/member] last post and search results, the link - https://askubuntu.com/questions/1056780/...showing-up

It is too complex for me to know how to assist though.
