Re: /var partition seems locked or read only

["der.hans" <deb-user@LuftHans.com>]

Am 23. Jul, 2014 schwätzte berenger.morel@neutralite.org so:

moin moin,

does /proc/mounts show /var/ as still being mounted rw?

Do you have large open files that have been removed? The filesystem will
show those as free space, but until the proceses holding the files open
have been stopped the disk space has not been freed.

If you had an aptitude run have problems check for old aptitude and dpkg
processes.

When aptitude has trouble downloading packages it should not try to
install them until they've been downloaded properly. Back in the day, I
would start an apt-get download and let it run all night on the modem
connection, then kill it in the morning. Then I would start it again the
next night and so on until all of the packages had downloaded properly.

Running out of space during package install can cause problems.

ciao,
