Public bug reported: Apt is erasing the previous contents of my terminal window. The output from commands that had been run prior to running apt were entirely erased from the terminal's historical record.
This is seriously bad etiquette, you should not ever take a dump all over the historical record of a terminal's output. The scroll-back feature is intentionally there so you can show a linear sequence of events. Back in the day consoles were connected directly to printers, and in fact some companies still do this for security auditing purposes, so you have to presume the terminal can only be written to... this is why it's called standard out. Overwriting is a serious no no. Also I'm not happy about apt breaking scripted execution (wtf were you thinking?), but this overwriting of the console record is a flagrant violation of proper etiquette. Please do the needful!
