Why Software updater wants to remove packages?

co flag

Ubuntu 21.10 Impish Indri 64-bit. As in the title: why does software update wants to remove discord (I need it and installed it for a reason, duh) and libpng12-0 (which, I know, is outdated, but I do need THIS EXACT version).

And what's these: libc++1-12 and libc++1 I don't even know (perhaps some dependencies for libpng12-0).

So I am confused over here. What do I do in order to keep my stuff and run the update?

21.10 has libpng16-16! :~) I guess it is not happy about the 10 year old libpng you need.

SP Flash Tool (software for flashing firmware onto MTK devices) needs 12-0 for whatever reason. So I need it as it is. However I do understand that the thing is old and outdated. So what about discord? Why on god's green earth the updater would like to uninstall discord?! And how can I keep everything I intentionally installed? Please don't suggest to upgrade anyway and simply reinstall removed packages.

Packages are removed when their requirements and dependencies *conflict* with the rest of the system. It's that simple. Looks like your Discord deb was tied to a specific version of a dependency. If so, that's a bad idea...and you just found out why. The easy way to keep Discord in this sort of situation is to use the Snap instead of the deb.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
