Update Manager - not finding "new features" [message #185847] Thu, 28 December 2006 04:04 Go to next message

Hi,

I'm not really a newcomer to Eclipse, having used it for a few years
without problems - but right now I'm having a newbie moment.

My Eclipse 3.1 would not see any new features in Update Manager after I
added a new Remote Site for ErlIDE. I then decided to update the whole
installation to 3.2.1.

After adding Remote sites for Subclipse, EPIC and ErlIDE, and checking
the Callisto (for CDT) and Eclipse update sites for search, I have the
same problem with 3.2.1: "No features found on the selected site(s)."

I've not had this problem before - I've always been able to install
Subclipse, CDT, etc. Does anyone have a clue why it's behaving this way?

TIA
--Toby

Found the problem.

At some point after last running update manager, I had manually changed
uids. I did not chown everything in /tmp, and there was a directory
/tmp/1427684339 that was owned by the old uid; apparently updates were
silently blocked because Eclipse could not write to it. That is, there
was no indication in the GUI (other than the misleading "No features
found" message), but there were console messages that pointed me to the
real cause.

It's not clear why Eclipse leaves that directory lying around between
runs, or how its name is generated (clearly not time/date/version/uid
based).
