[Thinlinc-technical] Firefox web access stuck at "HTML5 client is loading"

  hi Pierre (and all),

It seemed to be left-overs of a previous TL release on the server, which
seem not be correctly/completed cleaned up by installing a newer version of
TL :

(working on Ubuntu 14.04LTS)

1) I removed version 4.4
2) I installed version 4.5
3) web access was not working (hanging on the "HTML5 client is loading"

Correct procedure :

1) I removed version 4.5 packages
2) I removed entire /opt/thinlinc directory
3) I installed version 4.5
4) web access was working fine now !

So to me, this way of upgrading TL is not safe. After removing the TL
packages, there are files and scripts left on the master under
/opt/thinlinc from older TL version that break the correct functioning of a
new TL version that gets installed.

Only safe way (until corrected by Cendio) is the second way of working
(trashing any left-overs of TL on the server before re-installing).

kind regards,
