Ubuntu seems to have a trend of taking something that works under Debian and somehow messing that up. Upgrades are one thing but for a while we had separate instruction on how to make Yubikey tokens work under each version of Ubuntu (we used them as smartcards for SSH key auth), while Debian instructions stayed the same... Update was also hit and miss on user's desktop machines, for a while ubuntu had a nasty habit of installing new kernel upgrades... without removing old ones, which eventually made boot run out of space and poor user usually had to give it to helpdesk to fix. Tho tbh most of the problems in any distro with packages is "an user installed 3rd party repo that don't have well structured packages and it got messy".
