Answer 1

Remove var/generation , var/cache ,var/page_cache folder from your magento2 root directory and then run below commands in sequence.

• sudo chmod -R 777 var

• php bin/magento deploy:mode:set developer (set the mode of environment is developer)

• php bin/magento setup:di:compile(it will generate all the proxies and dependencies )
• php bin/magento setup:static-content:delpoy(it will deploy all the static content)
• php bin/magento cache:clean and php bin/magento cache:flush(clear the cache)

Note : Make sure your var and pub/static folder have writable permissions

Answer 2

You have to assign permission to var folder, 777 like we are changing in local with chmod -R 777 var

then this will work perfect, hope this will help,

Answer 3

run command:

sudo chmod -R 777 var/

and

sudo chmod -R 777 pub/

under magento2 root directory.
