Just noticed "2 Important updates available " when I click on install I see that they are - to "update login" and "update password" - call me paranoid but are these bona fide and genuine updates ? - I cancelled the update until such times as I can establish that these are genuine updates so would appreciate any assistance you can offer
Many thanks for your assistance Stevef, I have now updated my system accordingly
Ubuntu version 20.04 (and earlier) had a problem with the 2022-11-28 change.
Users of Linux Lite 5.x who applied the 2022-11-28 update will notice a further change for the passwd and login packages to address this.
Users of Linux Lite 6.0 will retain the 2022-11-28 update at this time. There may be a further change to bring all versions into line.
