update manager gives untrusted packages for installation - can't rid from update manager - won't install

[J. Paul Purdell]

The update manager reports there are 91 updates to install. After selecting the install button an error message appears which reads "Requires installation of untrusted packages" and then it states the packages are not from an "authenticated source". Why does the update manager have these packages available for installation if they are "untrusted" and not from an "authenticated source"? In the settings I have selected to download and install only authenticated packages. These untrusted installation packages keep appearing - won't go away. If they are untrusted, I don't want to install them. How do I get rid of them? Why were they offered in the first place? This must be a bug. Some of the installation packages are security updates. Thank you.

I had this same issue today.
Then I reload package information from Synaptic Package Manager.
After that Ubuntu Update Manager installed updates.

Even if this workaround works, I think there is a bug.

Thank you for your message. Ever since I discovered this bug I have not
been successful at installing these 91 updates. I think I reloaded package
information fron Synaptic Package Manager but I'm not absolutely certain
because I am very new to Ubuntu and Linux. Would you please detail for
everyone how one goes about reloading package information from Synaptic
Package Manager? I want to make sure I did this procedure correctly.
Thank you very much.

1. Open Synaptic Package Manager
2. Click Edit Menu
3. Click Reload Package Information
4. Then close Synaptic Package Manager
5. Open Update manager
6. Click Install Updates.

This is just a workaround and not a fix to bug.

To: Chamal De Silva: Thank you for your reply. Your "workaround" was successful except that I had to add one additional step. After closing the Synaptic Package Manager, the update manager would not open and was still showing (at that point) 101 updates. So, I tried rebooting the computer. After the reboot, the update manager did not show any updates. I selected the cog image in the upper right corner of the screen and "up to date" regarding updates was displayed. I checked it again now (as I write this) and the information reads "updates available". I will select it to see what happens. Oh no! It now shows the 101 updates to be installed again. I will try it. Maybe the additional 9 updates have some type of fix.
No, there was no fix. I still receive the same error message "requires the installation of untrusted packages" I tried installing but was not successful. I wonder if it would help to reinstall Ubuntu?
