[isabelle-dev] Access problems to repositories and NFS

Dear Isabelle developers,

since Thursday, there have been intermittent problems with access to our
chair's servers; in particular, lxbroy10 which most people use to pull
from/push to the Isabelle repository.

The precise circumstances are unclear to me and not everybody seems to
be affected.

Until the problems with lxbroy10 are resolved, please try lxbroy9 or
lxbroy8 as login nodes. The Isabelle repository should be available
there too.

In case these machines also don't work, please perform the following
steps which have been provided by the responsible admin:

1. Go to <https://cal46.in.tum.de/>
2. Log in using your regular credentials that you would also use for
3. Go to "Preferences", "Password"
4. Set a password. It can be the same password as before
5. Click "Change"
6. Re-try SSH login to lxbroy8 or lxbroy9

In case that still doesn't work, please reply to me privately and I'll
bundle and forward affected user accounts to the administrator.
