I have the following LaTeX code:
<code>documentclass[11pt]{book}
usepackage[default]{opensans}
usepackage{alltt}
usepackage[listings]{tcolorbox}
usepackage{xcolor}
newenvironment{generalSrcCode}
{vspace{5pt}
begin{tcolorbox}[
colback=lightgray,
coltext=black,
boxrule=0pt,
arc=5pt,
before skip=5pt,
after skip=5pt,
left=5pt,
right=5pt,
top=5pt,
bottom=5pt,
boxsep=0pt,
valign=center,
baseline = 0pt
]begin{alltt}color{black}ignorespaces}
{end{alltt}end{tcolorbox}
vspace{5pt}
}
begin{document}
noindent
Run the following commands in a terminal:
begin{generalSrcCode}
sudo apt install -y postgresql-common
sudo /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh
end{generalSrcCode}
noindent
Once you have run the above-mentioned commands,
end{document}

As you can see, there is a blank line at the end of the second command in the tcolorbox. I want to get rid of it and also center the content in the box vertically. Is this possible?
Thanks in advance
As you are anyway using a tcolorbox around the code, I would directly use a tcblisting:
<code>documentclass[11pt]{book}
usepackage[default]{opensans}
usepackage{alltt}
usepackage[listings]{tcolorbox}
usepackage{xcolor}
NewTCBListing{generalSrcCode}{}{
colback=lightgray,
coltext=black,
boxrule=0pt,
arc=5pt,
before skip=5pt,
after skip=5pt,
left=5pt,
right=5pt,
top=5pt,
bottom=5pt,
boxsep=0pt,
valign=center,
baseline = 0pt,
listing only
}
begin{document}
noindent
Run the following commands in a terminal:
begin{generalSrcCode}
sudo apt install -y postgresql-common
sudo /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh
end{generalSrcCode}

end{document}
