What I’ve found so far:
Using the salt method broke my update capability - 23.10 isn’t supported by Salt either, and it leaves a file ( /etc/apt/sources.list.d/salt.list ) that points to nonexsistant repositories.

Delete the salt.list file, and you should get your updates back.
As far as the rest of the list of updates you pointed to, they seem OK - I suggest pasting them one at a time in (The commands between &&'s can all be pasted in one after the other) and making sure you don’t get any errors. I just did that list (Minus the ‘quiet splash’ because I like to see boot) and am going to reboot. I’ll let you know how it goes.
…and it doesn’t seem to have done any harm. Wifi still makes connection fine, hid_sensor_hub is listed as blacklisted in syslog. Not saying it’ll raise the dead or anything, but it doesn’t seem to hurt.
