SQL SERVER 2017 | error al restaurar Base de Datos | Ningún conjunto de copia de seguridad seleccionado para ser restaurado

Tengo un problema al intentar restaurar una base de datos, desde que entro a la ventana de restaurar base de datos me sale un error diciéndome: “Ningún conjunto de copia de seguridad seleccionado para ser restaurado”. Sin ningún motivo me muestra este problema.

Sí selecciono mi bd no me deja proceder a la restauración, sigue el mismo mensaje de error.

¿Cómo lo soluciono? ¿a que se debe el problema?


Aquí una captura, del problema.

Ubuntu apt update error `Failed to activate service ‘org.freedesktop.PackageKit’: timed out (service_start_timeout=25000ms)`

On my Ubuntu 18.04LTS vm I run the command apt update and whilst running I get the following output:

user@user-VirtualBox:~/minitube$   LANG=C sudo apt-get update Get:1 http://security.ubuntu.com/ubuntu bionic-security InRelease [88.7 kB] Hit:2 http://ppa.launchpad.net/mc3man/mpv-tests/ubuntu bionic InRelease                        Hit:3 http://gr.archive.ubuntu.com/ubuntu bionic InRelease                                                            Get:4 http://gr.archive.ubuntu.com/ubuntu bionic-updates InRelease [88.7 kB]         Get:5 http://gr.archive.ubuntu.com/ubuntu bionic-backports InRelease [74.6 kB] Fetched 252 kB in 1s (345 kB/s)                               Error: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.freedesktop.PackageKit': timed out (service_start_timeout=25000ms) Reading package lists... Done 

And I want to fix the cause of the following error message:

Error: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.freedesktop.PackageKit': timed out (service_start_timeout=25000ms) 

Do you know how to do that?

How to fix an error while using command ‘import cv2’ in Python

Actually I have installed and downloaded Anaconda in my laptop. I am supposed to do a project on Face Recognition using OpenCV. I have downloaded and installed OpenCV in my laptop, but whenever I give ‘import cv2’ command in Jupyter Notebook or in Spyder, it throws a “ValueError: source code string cannot contain null bytes” error. What shall I do? How can I fix this?

Unable to modify file permissions.xml, get error Read-only file system

I have a rooted Galaxy S5 SM-G900V, lineage_klte, ARMv7 Processor rev 1 (v71), Kernel: 3.4.113-lineageos #1 SMP, Oreo 8.1 that a friend asked me to modify.

I need to modify the platform.xml file to allow the system to write data to the external sd card. I need the ability to modify this file. The current permissions are: rw-r–r– 1 root root, however I am unable to save any modifications.

I am unable to modify the file permissions and would like to know how to do so. Note, I am looking how to change the file permissions and not how to or what syntax to use in the xml file, or if it will allow me to have the system recognize the external sd card for saving data. I am perplexed on why I am unable to modify this file.

> adb devices  <-- verify I have the device > adb shell    <-- enter shell > su           <-- super user # ls -l drwxr-xr-x  17 root   root      4096 2019-03-20 10:26     system # cd system #ls -l drwxr-xr-x 20 root root     4096 2019-03-20 10:25 etc # cd etc  # ls -l  > drwxr-xr-x  2 root root     560 2013-12-31 21:23 permissions  # cd permissions  # ls -l  -rw-r--r-- 1 root root  9116 2008-12-31 18:00 platform.xml  # chmod 755 platform.xml  >> chmod: chmod 'platform.xml' to 100755: Read-only file system 

So, how do I change the file attributes for platform.xml allowing it to be modified? I thought that there was a hidden immutable attribute on the file but there is not(at least that I can determine).

Related question, is there any other website to post this question? Any help is most appreciated.

Connection error after attempting to upload or move a file with FileZilla

I’ve started using Putty and FileZilla on my windows 10 notebook to access a cluster server.

I was able to log in yesterday and had success moving, downloading and uploading some small files, but it suddenly aborted the connection after a tried to download a pbs file. So when tried to log in FileZilla with a SFTP connection it gives me a “Connection timed out after 20 seconds of inactivity” and with Putty it just gives me a black screen and then a Network error.

Today I could log in normally and then it happened again when a tried to upload a .fastq file.

I checked my Firewall and tried changing the timed out connection to 30 seconds, but it did not work.

I really need this to analyse some metagenomic data. Thank you!

Does “Not Found” error always mean the app is unpublished or not active on Play Store?

I am having difficulty finding some apps in Play Store. A lot of times, when I come across a link on the older posts of this website and I load it, I get “Not Found” error on Google Play. I explicitly get:

We’re sorry, the requested URL was not found on this server.

I do double check with the app on AppBrain and usually, it shows that XYZ app unpublished on some ABC date in the past, so I end up believing that the app is really dead on Play Store. However, sometimes, a user, whose post I deleted because of dead link tells me that the app is live on Play Store.

I do a check using Opera browser’s free VPN service (regions: Europe, Americas, and Asia), and also with a Chrome Extension for American/British VPN service. I again and again get the same dead link. I also ensure using Private Browsing to rule out browser caching.

Recently, a fellow moderator notified me that while I was not able to load the link, he could easily load the app Google Goggles on Play Store. AppBrain still shows the app is no more active on Google Play though.

Similarly, I came across the app MyAndroidTools which does not load in Google Play Store, also seems inactive on AppBrain, but had a fresh beta version, as seen on APKMirror.

How do I truly believe that the app is really dead for everyone? Alternatively, how do I know to whom the app is not dead, and how can I load at least the app’s page, let alone download it from Play Store?

Error in SharePoint hosted app: Add permission level to the list programmatically

I am trying to add permission to the list which I have created in my app. I am trying to give current user some permission to add update delete items from my list. I have used one article from MSDN site. And my code is as bellow:

function execOperation() {     debugger;     context = new SP.ClientContext(appweburl);     var factory =         new SP.ProxyWebRequestExecutorFactory(             appweburl         );     context.set_webRequestExecutorFactory(factory);     appContextSite = new SP.AppContextSite(context, appweburl);     var appContextSite2 = new SP.AppContextSite(context, hostweburl);      var siteColl = appContextSite2.get_site();     hostweb = appContextSite2.get_web();     context.load(hostweb);      web = appContextSite.get_web();     context.load(web);     user = web.get_currentUser();     context.load(user);     que_list = web.get_lists().getByTitle("MyList1");     context.load(que_list);     que_list.breakRoleInheritance(true, true);      var permissions = new SP.BasePermissions();     permissions.set(SP.PermissionKind.viewListItems);     permissions.set(SP.PermissionKind.addListItems);     permissions.set(SP.PermissionKind.editListItems);     permissions.set(SP.PermissionKind.deleteListItems);      // Create a new role definition.     var roleDefinitionCreationInfo = new SP.RoleDefinitionCreationInformation();     roleDefinitionCreationInfo.set_name('Manage List Items');     roleDefinitionCreationInfo.set_description('Allows a user to manage list items');     roleDefinitionCreationInfo.set_basePermissions(permissions);     var roleDefinition = web.get_roleDefinitions().add(roleDefinitionCreationInfo);      web.breakRoleInheritance(true, false);     // Create a new RoleDefinitionBindingCollection.     var newBindings = SP.RoleDefinitionBindingCollection.newObject(context);     // Add the role to the collection.     newBindings.add(roleDefinition);      // Get the RoleAssignmentCollection for the target list.     var assignments = que_list.get_roleAssignments();     que_list.breakRoleInheritance(true, true);     // Add the user to the target list and assign the use to the new RoleDefinitionBindingCollection.     var roleAssignment = assignments.add(web.get_currentUser(), newBindings);      context.executeQueryAsync(onSuccess, onFail); } 

I have just copied the code from that article. But when I run my app it give me error :

You cannot customize permission levels in a web site with inherited permission levels 

Any suggestions, What am I doing wrong?
Any help will be appreciated…! Thank you in advance…!
