I might have forgot to tell that I already tried with another hard 
drive, and the installer failed exactly the same way.

Before seeing your last email, I replaced the RAM with a known-good, 2GB 
this time. Again, I had an issue while doing the install during packages 
configuration.

I then try an install without desktop environment (only SSH, print 
server and usual system utilities) successfully. After reboot, `apt 
install task-lxqt-desktop` failed (LZMA error when unziping 
libreoffice-core_1%3a6.1.5-3+deb10u6_i386.deb and 
libqt5webenginecore5_5.11.3+dfsg-2+deb10u1_i386.deb). Removed packages 
from cache, did `apt install -f`, and those packages installed properly.

I then installed many packages, still no issue.

I will run debsums to know the state of packages files, and then run 
memtest86+ during 24h.

Thanks again,
