have been having software centre occasionally stop/fail to install stuff, for maybe 6-months+
it 'sticks' installing for hours, then i find it has closed, when i restart there's still the same packages reported as needing updating.
i found a work-round; installing packages in small groups.
i am reporting now as i have just noticed that software centre always 'sticks' showing 'golang' being installed.
separately installing everything EXCEPT 'golang' works, then 'golang' by itself, works.
seems that it could have always been updates to 'golang' when this happened.
