Check `systemd` version

systemd --version

My output was:

systemd 245 (245.4-4ubuntu3)
+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN2 -IDN +PCRE2 default-hierarchy=hybrid

For some reason, this version contains a bug and letting me can't go on my works. I decided to update it.

## Update Method

sudo nano /etc/apt/sources.list.d/ubuntu-focal.list

Add these sources

deb http://archive.ubuntu.com/ubuntu focal main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu focal-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu focal-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu focal-proposed main restricted universe multiverse

Update date apt

sudo apt update

Check Usable Version:

apt-cache policy systemd

My output was:

systemd:
Installed: 245.4-4ubuntu3
Candidate: 245.4-4ubuntu3.24
Version table:
245.4-4ubuntu3.24 500
500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
245.4-4ubuntu3.20 500
500 http://archive.ubuntu.com/ubuntu focal-security/main amd64 Packages
*** 245.4-4ubuntu3 500
500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages
100 /var/lib/dpkg/status

Now we can see there is a new version `245.4-4ubuntu3.24`. We can update it by

 sudo apt install systemd=245.4-4ubuntu3.24

Check `systemd` version again

systemd --version

There MY NEW VERSION go!

systemd 245 (245.4-4ubuntu3.24)
