Desktop R6 - systemd

[archemone]

hi, i'm new here. i have this problem:
this week a bubble came out on my screen which said that there are new updates for my system. i started the update, everything was ok, but once my screen went grey and everything stoped. i couldn't do nothing so i restarted my netbook. after restart system couldn't start so i tried it with the previous kernel. it started correctly. but the bubble came out again. table said systemd needs to update but it is impossible to update systemd. i checked the kernel, it says that there is the newest kernel in my system (... .44-2). but it is only the previous kernel running on my netbook (... .39).
what should i do to run RosaOS with newest kernel correctly?
i have a Toshiba NB500-108 netbook and Rosa Desktop with LXDE runs allways correctly on it till one year. without problems. this is the first time.
thanks.
