i just want to let you know that may be a problem with latest update
for now i just re-install linux mint so i can not provide any info anymore.
i Using firmware rtlwifi/rtl8192cfw.bin (grab it from dmesg). it work until i update today.
after i dig to a problem. i found that NetworkManager can not start it always failed
so, i think this problem is from NetworkManager (actually it has 6-8 services that can not start ex cups)
and only one errors that i see is about libidn and punnycode (i can not remember what actual text)
so, after i re-install i blacklist libidn update. and re-update other package
and it works now
so, i think libidn2.2 may be a cause of problem

Hello, mix5003.
You might like to post the screen output of the terminal commandline
inxi -Fxz, because it would help to know your basic system specifications in order to have an idea what precisely went wrong. Problem with the latest updates is not really precise enough.
Maybe, just maybe, you are a victim of one or boths blunders, which Ubuntu had to admit:
Ubuntu warnings: K4.15.0-60 buggy + Systemd 237-10.28 may cause network failures
Therefore, it would be nice to learn which systemd version precisely you are using as well.
Regards,
Karl

Which makes clear, again, how important it is to have at least one or two Timeshift snapshots. Or to freeze these vital system components:

Hm, if this should be correct, then maybe this thread is of interest to you:

You do not happen to use this PPA by any means?
