"Tried to start delayed item" ... "but failed" in output of apt-get install

I've recently started to use new distro (Linux Mint 21, which I've read is based on Ubuntu 22.04). And when installing some packages I often see many same lines near end of apt-get install output: "Tried to start delayed item" http...ubuntu jammy package-name "but failed" Web search for "Tried to start delayed item" "but failed" found only couple of links, with bugs (I saw only submission of bugs, no discussion). I also was not able to find "delayed item" for apt-get, what it is. What those delayed items are and what does the error mean? TIA
