I suspect you are right and I have handled it by rebooting. The problem recurs intermittently and only when the updates are security related. There have only been relatively few instances of the problem but when it happens I get error messages:
Could not get lock /var/cache/apt/archives/lock - open (!!resource temporarily unavailable) Unable to lock the download directory. Sometimes but not always also a message there is another app running which needs to be closed. As I have security updates set to install automatically, perhaps update manager is both trying to install the updates and also telling me to install the updates. If I try to install them (security updates) I usually get the problem. If I do not try to install but just close update manager the updates usually install. But not always and the security update for T-Bird on 8/21 is one case where the update did not then install. In that case I ended by rebooting, opened update manager, and installed the T-Bird update without difficulty. This is how I have managed the problem - rebooting when I get a notification of available security updates. When I reboot and then open update manager I sometimes (again) get notification that no security updates are available (the updates appear to have already been installed). Other times, as with the T-Bird update, that security updates are available and this time there is no installation problem. The problem is annoying but handleable except that I wonder and worry about possible security implications of having an update manager which is not completely consistent. Anyway, thanks for your help. feranick wrote: > It seems you might have multiple instances of update manager (or > synaptic) open.
