Ubuntu :: Kept Getting "gtk-update-icon-cache: The Generated Cache Was Invalid" Fault
Feb 17, 2010
i was looking for a way to stop my menus taking a few seconds to load my icons when i first open them and found a few guides suggesting using the gtk-upate-icon-cache command, but with the any colour you like icon theme i'm using (stored in my home folder .icons directory) i kept getting a "gtk-update-icon-cache: The generated cache was invalid." fault i used the inbuilt facility in the acyl script to copy the icons to the usr/share/icons directory and tried the command again, this time using sudo gtk-update-icon-cache --force --ignore-theme-index /usr/share/icons/ACYL_Icon_Theme_0.8.1/ but i still get the same error. i tried with several of the custom icon themes i've installed and only 1 of the first 7 or 8 i tried successfully created the cache.

openSUSE 11.3 with GNOME
Whenever I install a new application, that application's icon is broken (shows the generic "application" icon) until I run gtk-update-icon-cache on /usr/share/icons/hicolor. The package manager must not be updating it correctly, but for what reason I'm not sure.

I don't understand this error nor do I know how to solve the issue that is causing the error. Anyone care to comment?

Error: Caching enabled but no local cache of //var/cache/yum/updates-newkey/filelists.sqlite.bz2 from updates-newkey
I know JohnVV. "Install a supported version of Fedora, like Fedora 11". This is on a box that has all 11 releases of Fedora installed. It's a toy and I like to play around with it.

I was laughing about klackenfus's post with the ancient RH install, and then work has me dig up an old server that has been out of use for some time. It has some proprietary binaries installed that intentionally tries to hide files to prevent copying (and we are no longer paying for support or have install binaries), so a clean install is not preferable.
Basically it has been out of commission for so long, that the apt-get upgrade DL is larger than the /var partition (apt caches to /var/cache/apt/archives).
I can upgrade the bigger packages manually until I get under the threshold, but then I learn nothing new. So I'm curious if I can redirect the cache of apt to a specified folder either on the command line or via a config setting?

Is it possible to configure a cron script to update the packages in /var/cache/apt-cacher/packages? When a client machine updates a package, apt-cacher checks that it's cached package is up-to-date, and downloads a new version if it is not.
I'd like apt-cacher to check it's cached packages every night and download any updated ones, on the premise that since it exists in the apt-cacher cache, someone has that package installed and is going to want to update it. Is this possible? Does apt-cacher do this anyway, and I haven't noticed?

I'm working on a web site. I'm sometimes finding that when I update a file, some mysterious force intercepts my changes and refuses to let me see them. I have confirmed that this mysterious force is a server cache.By adding a "?" to the end of the URL, I can see the changes I've made. Is there a way to somehow force my Internet provider to update the server cache?

I just installed F9 and updated to F11 (fedora 11) and I updated the system because I couldn't get the media player working and then I installed all these packages for two days. I have tried yum clear cache and the rpm update. Here are some of the ones I tried:
rm -f /var/lib/rpm/__db*
yum update PackageKit
; yum clean all;
And this is the error:

I've been troubled by the high amount of RAM that is used by my Ubuntu desktop. Before I installed Ubuntu 10.04 (desktop, 64-bit) my system used around 500MB of RAM when no applications were open (just cold boot into the GNOME under 9.10). But when I installed Lucid, I've noticed that my used memory is now reported as 1GB or more as soon as I log into the system.
I want to figure out what is using all the extra RAM but I can't seems to find the culprit. I looked at all of the processes and numbers just don't add up. I exported the list of processes into a file and summed up the memory used by every process in a spreadsheet. The total came to around 700MB. Yet, both System Monitor and "free" reported the time that system was using over 1GB of memory. This means that at least 300MB of RAM are used but not by any process, at least as reported by "ps".

I read somewhere that i can clean cache memory with this comand:
Code:
david@lap:~$ sudo echo 3 > /proc/sys/vm/drop_caches
bash: /proc/sys/vm/drop_caches: Permission denied
The problem is that permission is denied as you see...

Whenever I plug-in my USB 8gb pendrive to copy a large file, it takes eons. Using Ubuntu 9.10 for AMD64. At first it copies a file at high speeds, because it's not actually writing to the USB but to the cache; at 500-700mb, the write cache is full and flushes, *while* still copying the rest of the file. Since the system is trying to access the USB in two different places at the same time, the transfer speed bunks down, often to 200-300kb/s. The final process, instead of taking 2 minutes, takes one hour.
This continues until 1.4gb, when the cache finishes the flush, the copy can continue streamlined and the last 200-300mb are copied again at quicker speeds. I've made a test, copying a 1.6gb file to the USB and waiting for the cache to get full. Once it happens, I copy another file of the same size to the USB at the same time, when it starts copying I cancel the previous copy - cancelling it could take 1-2 minutes, but once it's cancelled, the second copy goes amazingly quick since the pendrive doesn't have any access troubles anymore.
However, that means for the trick to work that I can't copy four 1.6 files to the 8gb pendrive, but only three. The fourth one would need an hour unless I start copying it just before the first three finish so the write cache is still not in use or something like that. So what I would want is that everytime I plug-in this specific USB drive (identified by its label or UUID), the automount parameters disable write caching for this drive. Is that feasible? Using fstab or how?

I'm trying to convert some of my old Pidgin-logs to Empathy's format, and I've run into an issue I can't figure out. The Empathy logfiles contain a "token", which is a sha1-hash of the user's avatar at the moment the message was sent.The avatars are stored (in my case) in ~/.cache/telepathy/avatars/butterfly/msn. All filenames contain the sha1-hash, and have no extension (such as jpg/png). Some avatars uses only the hash as filename, but some has the prefix "_3" before the hash.Does anyone know why some avatars are prefixed "_3"?

I've been advised to "clear the java cache", and to do so under Windows, one would open the java control panel. Of course, I'm using OpenJDK, and not Java's java.
Can anyone tell me how I would clear the java cache?

I am using Fedora 11 64-bit. The problem is, when I start to install any updates or new packages, the system return the following error:No package cache is available.The package list needs to be rebuilt.This should have been done by the backend automatically.
Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again.I am completely new to linux, meaning I have never, ever, used a linux based system. I have recently accustomed to myself with only the basic commands (ls, yum, help, g++ etc.)

I have a small older HP OB6000 laptop with F14 on it and only 10GB of disk.
I've been weeding out a lot of packages I don't need on it to carve more user disk space.
One of the biggest disk consumers is /var/cache/yum. My problem is that even after a yum clean all it still consumes over 450MB.code...

I found that one of my computers was issuing a DNS request to a domain on my local network every time I send a query. I've look around and saw several programs you could install for DNS local cache, but does it not come with some application by default? If it matters, I'm running Ubuntu 11.04 with DHCPD and Bind9.Also, I did add nameserver 127.0.0.1 to /etc/resolv.conf, and it's listed before my other nameservers.

Slackware64 13.0 I have a website that has been migrated to a new server. After a few days I'm still pointing at the old server and the hosting company have recommended that I flush my dns cache. A quick google for this in linux seemed to recommend restarting the nscd daemon but nscd -g tells me it's not running anyway. I connect to Virginmedia via wired ethernet to a Belkin N1 router so is there a way I can do this I wonder, either via Virginmedia or Slackware?

I use two ramdisks one mounted in /tmp the other mounted as /ramdisk /tmp is used as a temp store for apps which need temp space /ramdisk is used to store copies of read only databases for processing. Files in here can be 10-500Mb in size.
I suspect that the O/S may be caching the files stored in /tmp and /ramdisk and thus is not efficient. How can I check if the O/S is caching ramdisk files and if this is the case how can I prevent it? Is there an option to say 'dont cache /tmp' ?
