I don't think this has been implemented in MintInstall yet. But if u REALLY have to install multiple applications at a time, there are 2 ways i know of:
1) use synaptic package manager...u can tick mulitple packages....(this may be risky if you are new to linux as u may accidentally install random packages)
2) install the gnome-app-install by searching it synaptic or by typing this into the terminal:
- Code: Select all
apt install gnome-app-install
When installed, this application should appear in your menu somewhere as "Add/Remove" You can tick multiple applications that you want to install.
Hope this helps and good luck
