That looks like Squid is not actually running as the user 'proxy', or
you are not starting it from an account that can change itself to be
that effective-user.

Squid-3 should be started by the root user, it will downgrade its
permissions before opening ports and handling traffic.

That looks like the configuration for a UFS format directory, but
labeled as being a Rock format directory / database.

See the cache_dir documentation for what each one is supposed to be
configured with:

They packaged Squid-2 under the name 'squid' for many years, and
followed the 2.6/2.7 fork with that package name.
 while packaging Squid-3 as 'squid3'. Then when Squid-2 was dropped
Ubuntu migrated everyone to 'squid3' package.

The naming is finally getting back to being 'squid' with only latest
version available.

That error message existing means the line *does* exist in the
squid.conf file you are loading.

The lack of '#' at the beginning of some lines you quoted below means
that those lines *are* being passed to Squid as active config to use.

That is a piece of example documentation being used blindly without
reading the actual documentation it is part of.

It is not even docs about the cache_dir directive!

The reason the "..." exist is that the documentation is explaining how
to use *store_dir_select_algorithm*. The settings other than the shown
ones are irrelevant for that documentation and being skipped.

Hmm. The 'squid3' package should have config files at /etc/squid3/*

The 'squid' package has config files at /etc/squid/*

Is that an exact copy-paste of the output?
 Are the "..." characters really in your config file?

If yes, the problem is that somebody has mindlessly cut-n-pasted
incomplete example config line(s) into your squid.conf.

If no, then the problem is that you are hiding the broken piece of
config from us.

Either way you have something to fix.


> Squid Cache (Version 3.5.12): Terminated abnormally.

That is the version number from the Ubuntu 16.10 or later 'squid' package.

It should be started with the command 'squid', not 'squid3' as indicated
by the above lines.

Well, grep?

eg: grep -v "^[^#]" will show all lines which start with something other than 
a # - in other words, it will omit blank lines and comments.

"Suspect"?

How have you set up this VM?  Is there an actual device mounted on /ssd3, or 
is it just some directory name in your VM?

Please specify what yu mean by this - what is the "it" which "its" refers to 
above?

I recommend you stop using any graphical tool to try to manage Squid, remove 
the package, and then simply:

1. Install the Squid (maybe called Squid3?  I can't quite recall for Ubuntu) 
package using apt-get or aptitude.

2. Edit the config file /etc/squid/squid.conf to your needs.

Hope that helps,


Antony.

Impossible - otherwise it couldn't generate the error message "FATAL: Bungled

Thta is telling you that line 3467 of squid.conf starts with the directive 
"cache_dir".

Standard Ubuntu?  Which version?

Hm, okay, so that really does exist on your machine, then...

Er, what are those screenshots of?  It's certainly not the output of Squid, or 
its config file.

You can put your cache directories wherever you like.

Er, so /ssd3 is not an actual SSD, then?  What is it?

> default installation method using the setup wizard.

I'm suspicious that you may be used webmin, and we've had someone here on the 
list recently who installed Squid on Ubuntu along with webmin, and we then 
found out that the package maintainer had put the documentation file for 
squid.conf in place of the actual squid.conf.

It can still work (not everything is commented out) but it's *far* bigger than 
it needs to be, and is somewhat confusing to work with.

My guess is:

a) you have an email client which isn't correctly adding a plain text body

b) you do not have a directory /ssd3 on your computer

If either of those is incorrect, please follow Yuri's request to post your 
squid.conf (without comments or blank lines, please), but also add the output 
of:

ls -al /ssd3

from your machine.
