====== Kali Linuxc: apt error - File has unexpected size ======

===== problem =====

The following error is displayed when updating via [[wpde>apt-get]] :

<code text>
Err:3 http://http.kali.org/kali kali-rolling/main amd64 gzip amd64 1.8-1+b1
File has unexpected size (225568 != 115516). Mirror sync in progress?
</code>

===== Workaround =====

The apt update via [[wpde>http]] should be changed to [[wpde>https]] :

<code bash>
echo "deb https://http.kali.org/kali kali-rolling main non-free contrib" > /etc/apt/sources.list
apt clean
apt update
apt upgrade
</code>

Alternatively, the [[wpde>Nano_(Texteditor)]] can be used, but care must be taken to ensure that the http source is commented out.

The sources.list should then look like this:

<code text>
# See https://www.kali.org/docs/general-use/kali-linux-sources-list-repositories/
#deb http://http.kali.org/kali kali-rolling main contrib non-free

# Additional line for source packages
# deb-src http://http.kali.org/kali kali-rolling main contrib non-free
deb https://http.kali.org/kali kali-rolling main non-free contrib
