I am running 19.10 on a Lenovo flex 11 and all seems to be working smoothly. I regularly check for updates and often get something new installed apparently. Well, today I checked for updates and get the message "Failed to load repository information". My network connection is good...hello, my question is getting in here...so what is going on? Fetching e-mail works, surfing the web works, streaming works, but am unable to download repository information. What's up? results of update attempt:

my ignorance is nearly complete, but it appears to me that something may be lacking in the place where updates live - I am grateful for the assistance I get here.
