ubuntu update to 18.04 error found when loading /etc/profile cannot set LC_CTYPE, LC_MESSAGES, LC_ALL to default - locale

Question

After updating from ubuntu 16.04 to 18.04 I receive the following warning: error found when loading /etc/profile cannot set LC_CTYPE to default locale. The warning message also lists LC_MESSAGES and LC_ALL as having the same problem.
Here is my /etc/profile
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ "${PS1-}" ]; then
if [ "${BASH-}" ] && [ "$BASH" != "/bin/sh" ]; then
# The file bash.bashrc already sets the default PS1.
# PS1='\h:\w\$ '
if [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi
else
if [ "`id -u`" -eq 0 ]; then
PS1='# '
else
PS1='$ '
fi
fi
fi
if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
when I tried ran sudo dpkg-reconfigure locales, it returns...
perl: warning: Setting locale failed.

I now can run a program that required locale, but the update-locale complains about invalid locale settings.
I'm over my head here. Please help.

Answer 1

After looking at the last Error message listed in my question, I noticed that LC_ALL was being set to LC_ALL="en_US.UTI-8". I edited the /etc/default/locale and changed the UTI to UTF and now everything appears to be working. I'm not 100% sure that the locale-gen command assigned LC_ALL to UTI... I don't believe I did that.
In any event my solution is sudo locale-gen, edit the /etc/default/locale to
LC_CTYPE="en_US.UTF-8"
LC_ALL="en_US.UTF-8"
#LANG="en_US.UTF-8"
and problem solved.

I had an issue similar to this along with multiple others, my locale was all jacked up, autocompletion was haywire, dpkg was throwing errors on installs. couldnt get anthing to change by unset or updating locale the problem was missing directory
/usr/lib/locale/locale.archive
made sure default locale file
/etc/default/locale
was correct then ran sudo locale-gen and it updated everything correctly
