Setting up mysql-server-5.7 (5.7.22-0ubuntu0.17.10.1) ...
mysql_upgrade: Got error: 2002: Can't connect to local MySQL server through     socket '/var/run/mysqld/mysqld.sock' (2) while connecting to the MySQL server
Upgrade process encountered error and will not continue.
mysql_upgrade failed with exit status 11

it doesn't matter what i want to do. remove, upgrade, install an app, remove mysql-server itself, in all situations i get this error.

I have always moved the window to another workspace using ctrl+alt+shift+ArrowKey.

But now with Ubuntu 17.10 I can't do this. And the worse part is, alt+TAB is tabbing through all the windows not just the windows open in this workspace.

I have compiz, I have tweaktools, I have tested all combinations from its documents, I have asked in #ubuntu irc channel, nothing seems to be working.

I have ran sqlite3 from terminal but have problem exiting it.

this is how i have ran it:

sqlite3 database.db

i have tried CTRL+C but it wont exit, i have tried ESC, close(), exit() and it doesn't let me go.

I use multiple programs in different categories.(Emacs, terminal, Firefox, music player, IRC client, virtual box, ...)

I was curios, if it was better for my old and slow Ubuntu Desktop to use work-spaces instead of minimizing programs and switching to them? I have seen people running dozen Firefox instances each with multiple tab's open but each Firefox instance is on different work-space.

Does using work-spaces, like that, help with using resources or that just need a very powerful peace of hardware?
