Comment 2 for bug 1917960

Lubuntu daily QA-test (live) on
- hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)

I saw @lynorian's comment on #lubuntu-devel, so

- opened `pcmanfm-qt` & navigated to an installed directory (lubuntu 20.04 /home/guiverc/ directory)

- selected a text file (`calamares-settings-ubuntu_20.04.2.dsc`)
- right click & selected "compress"
(a dialog here that selected the type & location for result, .tar.gz but I didn't care; did it for variations I tried too)

It opens a PROGRESS window and gets to 50%
"Adding file /home/lubuntu"

then

"ERROR
Failed to execute the command (OK)"
