my Asus laptop (os 18.04) is acting funny

I'm going to try and copy some of the messages as I tried booting up.

/dev/sda7 contains a file system with errors, check forced.
[ 4.756102] random: crng init done / 3.9%
[ 4.758603] 7 urandom warning(s) missed due to ratelimiting
Inodes that were part of a corrupted orphan linked list found.

/dev/sda7 UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY.
(i.e., without -a or -p options)
fsck exited with status code 4
done.
Failure: File system check of the root filesystem failed
The root filesystem on dev/sda7 requires a manual fsck

BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3.3) built-in shell (ash)
Enter "help" for a list of built-in commands.

(initramfs) fsck
fsck from util-linux 2.31.1
(initramfs)_

now what do I do?

It says it needs a "manual fsck"

I need commands. I know I'm not giving much help here but when someone shows up I can give more if you ask the right questions

so I wanted to play a DVD I own which happens to be "restricted", copy-righted or whatever it's called.

so I searched and found this: https://askubuntu.com/questions/1052993/how-to-install-libdvdcss-so-2-library-to-ubuntu-18-04#
namely:

sudo apt install libdvdnav4 libdvdread4 gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly libdvd-pkg
sudo dpkg-reconfigure libdvd-pkg 
sudo apt install ubuntu-restricted-extras

I wrote the commands exactly as written in that page but one seemed to be going on for a long time and I cleared the terminal (maybe that was wrong. derp)

anyway, I got this message:

debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable

I've got Ubuntu 18.04 right now. I seem to recall that an earlier version let me play that DVD with no problem. Probably because those libs already came with the distro or because somehow I installed the libs, who remembers.

what can I do to fix this dopey problem? Should I reboot and try again?

So I have Ubuntu 18.04 (for the last bunch of months). Works great, no complaints

Recently, after normal updates I get this message about using "Livepatch". I'm guessing this is ok, but I'd like more useful info.

I'm guessing it's a security thing.

this guy has wonderful videos. This is one:

Let me extend my best wishes for the holiday season - Happy Festivus and Happy Solstice

Even though this video came out months ago, I saw it recently because of the election in Alabama. Damn, it's funny...... Let's all sing along -

it snowed today so I ran out with some of my little LEGO buddies and took pictures

I have a friend who makes Excellent drone videos.....So, here's one to kick off the topic

SO, can I assume not being able to alter your profile (settings) is a known issue?
