Strange problem with CentOS 7 and guest additions in VirtualBox
by Nicolas Kovacs 29 Sep '17

29 Sep '17

Hi, I'm having a very weird problem with CentOS as a VirtualBox guest. Let me explain it step by step. tl;dr: I can install VirtualBox Guest Additions and configure a fullscreen 1280x1024 graphical resolution on a full install, but not on a reduced install with a lightweight window manager. Here's what I did. 1. Install vanilla CentOS 7 with KDE. 2. Boot to reduced 1024x768 resolution. 3. Install gcc, make and kernel-devel. 4. Build VirtualBox Guest Additions. 5. Reboot to full 1280x1024 resolution. ==> perfect On a vanilla desktop installation, this works perfectly. Now here's my second attempt. 1. Install minimal CentOS 7. 2. Install X11: yum groupinstall "X Window System" 3. Install WindowMaker from Nux repo. 4. Launch WindowMaker (startx) to reduced 1024x768 resolution. 5. Install gcc, make and kernel-devel. 6. Build VirtualBox Guest Additions. 7. Reboot and still have a reduced 1024x768 resolution. ==> meh I made another attempt with Xfce instead of WindowMaker (yum autoremove WindowMaker && yum groupinstall Xfce), but with the same result. Any idea what's going on here?

Thunderbird in CentOS 7.4
by Alice Wonder 29 Sep '17

29 Sep '17

With the current Thunderbird I can not connect to one of my IMAP servers that uses a self-signed cert. Virtually identical IMAP servers that use CA signed certs work I was a bit out of date when I updated to 7.4 and was running Thunderbird 45.6.x and it worked. When I connected from evolution (which I do not like) it worked. When I connected with my laptop still running 45.6.x it works. so - I rebuilt thunderbird 45.8.0 from 7.3 updates (newest that isn't 5x.x.x series) and did an --oldpackage update with RPM and it works again. When rebuilding the old thunderbird in mock I had to add the following: BuildRequires: dbus-glib-devel Either the build system used by CentOS automatically includes that, or a build dependency use to pull that it but no longer does. Anyway if anyone is having a similar problem, that's a solution. -=- This is what I see in the mail server log when current CentOS thunderbird tries to connect: Sep 25 20:17:49 librelamp dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=2600:1010:b064:f260:e83e:562d:2316:18df, lip=2600:3c01::f03c:91ff:fee4:310c, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca: SSL alert number 48, session=<u7agQAlasK8mABAQsGTyYOg+Vi0jFhjf> --- Since it works with current evolution and with older thunderbird, I assume it is a bug in current thunderbird when the server is using a self-signed cert. Don't know if same thing happens on pop. I use IMAP on 143 using starttls

These packages are following the upstream Gluster Community releases, and will receive monthly bugfix updates. Gluster 3.12 is a Long-Term-Maintenance release, and will receive updates for approximately 18 months. The difference between Long-Term-Maintenance and Short-Term-Maintenance releases is explained on the Gluster release schedule page: https://www.gluster.org/community/release-schedule/ Users of CentOS 6 can now simply install Gluster 3.12 with only these two commands: # yum install centos-release-gluster # yum install glusterfs-server The centos-release-gluster package is delivered via CentOS Extras repos. This contains all the metadata and dependency information, needed to install Gluster 3.12. The actual package that will get installed is centos-release-gluster312. Users of the now End-Of-Life Short-Term-Maintenance Gluster 3.11 will automatically get the update to Gluster 3.12, whereas users of Gluster 3.10 can stay on that Long-Term-Maintenance release for an other six months. Users of Gluster 3.8 will need to manually upgrade by uninstalling the centos-release-gluster38 package, and replacing it with either the Gluster 3.12 or 3.10 version. Additional details about the upgrade process are linked in the announcement from the Gluster Community: http://lists.gluster.org/pipermail/announce/2017-September/000082.html We have a quickstart guide specifically built around the packages are available, it makes for a good introduction to Gluster and will help get you started in just a few simple steps, this quick start is available at https://wiki.centos.org/SpecialInterestGroup/Storage/gluster-Quickstart More details about the packages that the Gluster project provides in the Storage SIG is available in the documentation: https://wiki.centos.org/SpecialInterestGroup/Storage/Gluster The centos-release-gluster* repositories offer additional packages that enhance the usability of Gluster itself. Utilities and tools that were working with previous versions of Gluster are expected to stay working fine. If there are any problems, or requests for additional tools and applications to be provided, just send us an email with your suggestions. The current list of packages that is (planned to become) available can be found here: https://wiki.centos.org/SpecialInterestGroup/Storage/Gluster/Ecosystem-pkgs We welcome all feedback, comments and contributions. You can get in touch with the CentOS Storage SIG on the centos-devel mailing list (https://lists.centos.org ) and with the Gluster developer and user communities at https://www.gluster.org/mailman/listinfo , we are also available on irc at #gluster on irc.freenode.net, and on twitter at @gluster .

Semi-OT: hardware: NVidia proprietary driver, C7.4
by m.roth＠5-cent.us 28 Sep '17

28 Sep '17

This is really frustrating. I've got a server with two K20c Tesla cards. I need to use the proprietary drivers to use the CUDA toolkit. Btw, I had no trouble at all with building for CentOS 7.3 I have what NVidia claims is the correct driver package, a 340 series. It appears to build, but then fails to load. The only error I see is "no such device", which makes no sense to me, esp. since it says nothing whatever else. I've gone through the install log, and there are a bunch of Note:, and warnings, but the later I think are all about comparing signed and unsigned integers. And lsmod shows no nvidia drivers registered, but the logs claims that Error: Driver 'nvidia' is already registered, aborting... Anyone got any ideas? mark

Centos 7 Mate desk top
by Pete Geenhuizen 27 Sep '17

27 Sep '17

I upgraded to C 7.4 from C 6.9 on my laptop and all was well. As with C6 and the other C7 hosts that I have, if launch a terminal from the desktop it opens in [ user@host Desktop ]$ which is just fine. I restored parts of my C 6.9 home into C7.4 and now everything shows up on my desktop and when I open a terminal it now opens up in [ user@host ~ ]$ Obviously I overwrote the setting, that controls where the terminal opens. I've searched high and low but for the life of me I can't determine where that parameter is set. I've done some searches but haven't been able to get the right incantation that would yield an answer Does anyone know how I can resolve this dilemma?

Hi, folks, Well, still more fun (for values of fun approaching zero): 1. Went to install CUDA 9.0... well, gee, there is *no* CUDA 9.0. Even though I installed the 9 repo, all that I get is 8. I've used their webform, and an waiting on a reply. 2. I remove all nvidia packages. 3. It appears that the kmod-nvidia is what I need; that's what nvidia-detect says. So I try to install... bzzt, thank you for playing. a: uname -a: 3.10.0-693.2.2.el7.x86_64 #1 SMP Tue Sep 12 22:26:13 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux b: Installing : kmod-nvidia-384.90-1.el7_4.elrepo.x86_64 1/2 Broadcast message from systemd-journald(a)lyon.cit.nih.gov (Wed 2017-09-27 11:43:12 EDT): dracut[32409]: /lib/modules/3.10.0-693.el7.x86_64//modules.dep is missing.

yum update problem - dependancy problem
by Gary Stainburn 26 Sep '17

26 Sep '17

I'm sure this is a FAQ, and a simple answer is available, but I've not managed it yet. I've tried all of the RPM database tidy routines. I've tried uninstalling the libblueray1 library but the ever growning dependency tree was too big. For a while I've been updating using the command yum -y --skip-broken --exclude rpcbind update which I though t was working, but the list of rpm's not updated is ever growing so i need to find a solution. Here is the output from the yum update. I've remove the bulk of the output for brevity but I can include it if needed.

Re: [CentOS] yum update problem - dependancy problem

You have a conflicting package installed from repository @atrpms. You need to remove that package and/or disable that repository to get past the dependency issue. 'Skip broken' is not going to handle this situation nor will any other set of yum options.
