Package: coreutils
Version: 8.30-1
When using "apt-get" to install, remove and/or purge packages and piping
output to "tee", a minor output alignment issue appears.
Depending on terminal dimensions, the wrong aligned lines are different.
Due to mail line break, the examples below do not show it exactly.
In case of 237 terminal columns,
"Selecting previously unselected package net-tools."
is shifted to the visual end of the line above.
In case of 160 terminal columns,
"Need to get 0 B/248 kB of archives."
is shifted similarly and
"After this operation, 1,002 kB of additional disk space will be used."
is shifted again to the end of the already shifted line above, so there
is a large overall gap.

The issue appears independently of used "coreutils", Debian and device
used, at least according to our tests done. And of course it appears
independently of the actual handled APT package, as long as something is
actually installed or removed.
So it seems to be a general issue in how "tee" handles it's input or
catches terminal dimensions. Properly this could be fixed as well
"apt"-side, but for now I think it is better investigated "tee"-side.
