When self-update fails/is aborted, upper “Apply updates” button gets active again + ANOTHER ISSUE

[carlosmintfan]

Describe the bug When mintUpdate shows: “A new version of the update manager is available”, you click on “Apply the Update” but then cancel, the “Apply updates” button next to the refresh button which isn't active first as we should use the lower “Apply the Update” button - gets active again!

Screenshots

To Reproduce Steps to reproduce the behavior:

1. If you already have the latest version of mintupdate and mint-upgrade-info packages so mintupdate doesn't show the self-update screen, do the following:
2. Open file manage
3. Go to /var/lib/apt/lists
4. Right-click an empty area and choose “Open as root”
5. Open file packages.linuxmint.com_dists_vera_main_binary-amd64_Packages
6. In Text Editor, search for Package: mintupdate (Look if it's line 1225)
7. In the next line, replace Version: 5.9.7 with Version: 5.9.8 (replace the 7 with an 8 so APT thinks a new version is available)
8. Save the file.
9. Quit update manager from systray (if it's running).
10. Open it from the menu.
11. See that upper “Apply updates” button is inactive (as it should, use the lower “Apply the update”button)
12. Click on “Apply the update”, but then abort.
13. See that upper “Apply updates” button got active again.

Expected behavior The “Apply the update” button next to the refresh button should stay inactive when a self-update is available, even if it failed/was aborted.
