Re: [Trisquel-users] Upgrading to Trsquel 8 From an Ubuntu 14.04 Trisquelized System

Sorry, I didn't mean to imply that you were using unity. I mean that I am  
trying to use unity on Trisquel and am encountering the same errors. Those  
GTK plugin errors are not a problem specific to the MATE desktop environment  
or specific to upgrade installs. The icon size issue is a problem with the  
default icon theme I think, try changing it to something else,  
https://trisquel.info/en/issues/24141 this bug report was filed. As for the  
error popup, I don't know what that broken applet does? If you choose delete,  
does the error ever return?
