Public bug reported:
I have used Unix for 50 years, starting with V6/PWB, and I have used
Linux for 25+ years, different distros, RH or Suse at work, [k]ubuntu at
home, mostly. I never thought 'ls -l' could ever be broken but it is on
kubuntu 26.04, the worst Linux release ever (even though it's not
officially out). So many things broken, worst of all plasma, which
crashes any time the screen is turned off, is totally messed up when it
comes to window sizes and positions, etc... An abominable failure, so
far. But, to get back to 'ls', it looks like the MOST basic tool of all,
for ANYONE developing any software on Linux, is Valgrind! The 'ls' bug
is not a catastrophic failure, like the entire release as a hole, but
it's symptomatic. The space between the mode strings and the link count
sometimes is ridiculously large, for some reason. For some other insane
reason, /bin/ls is now a link to some fargo implementation of many BASIC
CRITICAL tools. Really? Whose idea was that??? Anyway, running valgrind
shows some OBVIOUS out-of-bound or otherwise invalid memory reads! And,
sometimes, the command actually works, when run with valgrind, sometimes
it DOESN'T even work at all! Use AI if you can't find any competent
basic developers!

What are all these spaces for??? As I said, the MOST BASIC testing could reveal
this issue!
As much of a nightmare it is to go back to 24.04, I am doing this soon
because it's clear that [k]ubuntu has lost its way!
