Xubuntu software update failed

Question

I tried to make update on my system (4.15.0-29-generic #31-Ubuntu SMP Tue Jul 17 15:37:27 UTC 2018 i686 i686 i686 GNU/Linux ) via software updater but the update failed. So I tried to make the update via apt-get command but also not successfully. There was this output:

Do you want to continue? [Y/n] y Get:1 http://cz.archive.ubuntu.com/ubuntu bionic-updates/main i386 ubuntu-release-upgrader-gtk all 1:18.04.24 [9 360 B] Get:2 http://cz.archive.ubuntu.com/ubuntu bionic-updates/main i386 ubuntu-release-upgrader-core all 1:18.04.24 [24,3 kB] Get:3 http://cz.archive.ubuntu.com/ubuntu bionic-updates/main i386 python3-distupgrade all 1:18.04.24 [105 kB] Fetched 139 kB in 0s (881 kB/s) Extracting templates from packages: 100% Preconfiguring packages ...

What was wrong?

Thank you

Check, if you have all needed folders in enviroment PATH like this:

# sudo echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

If not, you need correct this through adding appropriate folders to PATH variable.

Additionally check syntax at this file:

# sudo nano /etc/environment

All missing a " must be there.
