E: Unable to locate package mysql-workbench-community

snap install mysql-workbench-community

the problem that all snap packages are sanboxed and need to get permission to access local files & connect to DB.

Cannot connect MySQL Workbench to MySQL server

access files

or install dbeaver which is more stable.

If you want to install Mysql Workbench Just run this command in terminal

sudo apt install mysql-workbench

You are good to go with Mysql Workbench

For Ubuntu 20.04:

sudo snap install mysql-workbench-community

Happy Ubuntu!

At the time of my wrinting it seems that only a snap version is available:

sudo snap install mysql-workbench-community
