There must be a log somewhere. Enuf disk space
?
/target/var/log/anaconda.log ?
https://wiki.deepin.org/index.php?title=System_log
Oh, there seems to be a bunch of DDGoo search results;
add more keywords to narrow down: deepin "installation failed"
Ctrl-alt-f2 &watch ps/top: then strace last process before dies
Often, there's console msgs in one those f# chvt's, like f4
Some clever cmds on target fs to find
the very last file written.
Try the other 291 on DistroWatch first, then go back to deepin
Linux is
NO fun
(for me) if not broken
