squid only partially working WHY ?

[Ian A Taylor]

Oli

Thank you for your reply

on compute-0-2
initially
sudo snap get system proxy.http & sudo snap get system proxy.https  were 
blank

So I set them with
sudo snap set system proxy.http=http://10.1.1.1:3128
sudo snap set system proxy.https=http://10.1.1.1:3128


sudo snap get system proxy.http
http://10.1.1.1:3128

sudo snap get system proxy.https
http://10.1.1.1:3128


I restarted snapd on compute-0-2

sudo systemctl status snapd

Then I run
snap find test

which resulted in

error: cannot search: got unexpected HTTP status code 500 via GET to
"http://snaps.spark.internal/v2/snaps/find?architecture=amd64&confinement=strict%2Cclassic&fields=base%2Cconfinement%2Ccontact%2Cdescription%2Cdownload%2Clicense%2Cprices%2Cprivate%2Cpublisher%2Crevision%2Csummary%2Ctitle%2Ctype%2Cversion%2Cwebsite%2Cstore-url%2Cmedia%2Ccommon-ids%2Cchannel&q=test"


On spark:/var/log/squid/access.log I see

FYI 10.1.1.252 is compute-0-2

so whatever is wrong, that didn't solve it
