DietPi-Globals | G_AGX: Tiny output format issue

[MichaIng]

Just a tiny visual:

Observed this already on all systems and distros, VMs and RPi, seems to be an issue in how G_DIETPI-NOTIFY handles the APT removal output. See the large gap in front of After this operation and doubled (Reading database ...). This exactly shows up the same on every G_AGP:

The following packages will be REMOVED:
  libasound2* libasound2-data* libfftw3-single3* libgomp1* libncursesw5*
  libsamplerate0* libtinfo5*
0 upgraded, 0 newly installed, 7 to remove and 0 not upgraded.
                                                              After this operation, 6,826 kB disk space will be freed.
(Reading database ... 17317 files and directories currently installed.)                                               (Reading database ...

Yep, confirmed the extra space.

Hmm of course we do not pipe APT output through G_DIETPI-NOTIFY, just echo colour code around and run non-interactive... Will do some tests about which step causes the format issue.

Otherwise ignore, it's really just a tiny one.

Found tee to be the problem:

• The same format issue with upgrade and purge, in something gets actually removed or installed.
• Color, DEBIAN_FRONTEND/noninteractive, apt instead of apt-get and other options have no effect.
• Sadly I didn't find something about it via web research, thus no solution besides not using tee.
• Only idea I have (besides leaving as is, as it's just minor visual), to completely forward output to file and just show G_DIETPI-NOTIFY -2 processing message instead.

I opened a ticket on Debian bug tracker: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913083 ... sh*t, many many language mistakes inside 🤣 ... better reread first, before sending...

• Lets see if the maintainers/devs pay attention on such a minor visual-only issue 🙂. Since we found other tee related output issues, perhaps all of them can be solved at once, e.g. by using another terminal dimension estimation method.

Issue actually resolved with apt-get -q/-qq options (that we use now in most cases), which prevents processing related output:

No need to track this and the bug report any longer, since it is very minor. Will inform here, if the bug reports get any reply, but will mark this issue as closed.
