Good afternoon,

I am trying to setup squid with SSL inspection.  I'm currently running the
following OS and squid versions.
*lsb_release -a*
Distributor ID: Ubuntu
Description: Ubuntu 18.04.1 LTS
Release: 18.04
Codename: bionic

*squid -v*
Squid Cache: Version 3.5.28
Service Name: squid

This binary uses OpenSSL 1.0.2n  7 Dec 2017. For legal restrictions on
distribution see https://www.openssl.org/source/license.html

configure options:  '--enable-linux-netfilter' '--enable-icap-client'
'--enable-ssl' '--with-filedescriptors=65536' '--with-large-files'
'--prefix=/usr' '--localstatedir=/var' '--libexecdir=/lib/squid'
'--srcdir=.' '--datadir=/share/squid' '--sysconfdir=/etc/squid'
'--enable-ssl-crtd' '--with-openssl' --enable-ltdl-convenience

When I start squid or check squid while using sudo I get the following
errors.
*squid -s*
WARNING: Cannot write log file: /var/logs/cache.log
/var/logs/cache.log: Permission denied
         messages will be sent to 'stderr'.

*systemctl status squid*

The SSL part of my config is:  (I can and will post more of the squid.conf
file if needed)
http_port 3128 ssl-bump cert=/etc/squid/ssl_cert/proxyCA.pem
generate-host-certificates=on dynamic_cert_mem_cache_size=4MB

acl step1 at_step SslBump1

ssl_bump peek step1
ssl_bump bump all

sslproxy_cafile /usr/local/openssl/cabundle.file

I'm lost and appreciate any help.

Thank you
Mike
