How do I restore the default repositories?


There is no Apt directory in /etc. I have no idea how it got that way. I made an apt folder in /etc, now I need to know what should be in it.

Update: Ok I am getting closer. I created the directories that Synaptic is looking for but now I have an authentication problem:
W: GPG error: xenial-updates InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 NO_PUBKEY 3B4FE6ACC0B21F32
W: The repository ' xenial-updates InRelease' is not signed.
W: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
W: See apt-secure(8) manpage for repository creation and user configuration details.

How can I get the public...

Git is a distributed version control system which help people to work on the same documents (often code) at the same time, and without stepping on each other’s toes.We can easily switch in between the branches and commit the update to central master repository.

GitHub is a most popular/known Git service providers like bitbucket. Git is mostly known by GitHub service over the web. As part of moving all GitHub repositories to my owned GitLab hosted Server, I need to take backup of all repositories prior to delete it from the Git account.

Backing up Git repositories

a. Method 1 [ Using –bare parameter]

Eg: git clone –bare

[root@rc090 git_test]# git clone --bare
Cloning into bare repository 'Camper.git'...
remote: Reusing existing pack: 20, done.
remote: Total 20 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (20/20), 2.78 MiB | 187.00 KiB/s, done.

If you would like to restore the DNS configuration of your domain to the TransIP default values (for example after buying a web hosting package), this is what you need to do:

Go to Domain & Hosting in the Control PanelChoose your domainUnder "Advanced domain settings" you will find your DNS settings./li>Click on the 'Copy from' dropdown menu and select the 'TransIP default DNS-settings'Click 'Save' to confirm the changes

Keep in mind that changes in DNS settings and nameservers may take up to 24 hours to be processed worldwide. This 24 hour period is required because DNS entries are cached (usually in 24 hour periods) and your ISPs nameservers may contain the old nameservers. We are not able to speed up the process, but usually these changes are propagated within several...

Hello Eric,

I am here again trying to figure out why the 10.11.6 Combo Update still will not install. I have reduced storage by moving large files off-site but I don't think the problem is with space because I have more than enough space for the approximately 1.5 GBs required for the install. Other people in the community seemed to have had the same problem. An error message says, "OS X El Capitan Update can't be installed on this disk. This volume does not meet the requirements for this update." I don't know which particular requirement it does not meet. Perhaps it's something obscure?? I completely removed the question mark icon from the dock as Barney suggested, though I suspected that would not really provide me with the complete solution, and it hasn't. Now I have additional problems with getting into my email app, though that is likely a separate subject. (It does not accept my new password, or my old ones for that matter.) I really need to get this calendar issue...

Using the restore command

To retrieve backup copies of your files from a Tivoli Storage Manager (TSM) server or backupset, use the restore command. You can specify the source directory or individual file to restore, or you can choose the files from a list. You can also choose whether to restore the files to their original directory, or to a different location. By default, restore restores all subdirectories from the source you choose; to change this behavior, use the preservepath option.

Using the preservepath option

You can specify how much of the backup's path structure is reproduced with restore by using the preservepath option. Use -subdir=yes to reproduce the entire directory structure of the source location in the restoration. If directories in this structure do not exist in the target location, they are automatically created.

You can use preservepath with:

Close Firefox and launch its safe mode dialog box by clicking on Start -> Run and typing in 'firefox -safe-mode' (without quotes) OR by clicking on start > programs > mozilla firefox > mozilla firefox (safe mode).

After it restarts uninstall the add-ons/themes (if you don't want them) from Tools > Add-ons, select them and hit 'uninstall'

However, if you wish to have Clean Fresh Firefox then uninstall it completely and reinstall it.

This is how you uninstall firefox completely:

1)Uninstall firefox from the add/remove control panel (Start-> Run and type 'appwiz.cpl' (without quotes) or 'control appwiz.cpl' if you're in win9x and hit OK. Select mozilla firefox from the list and hit remove.

2)Now delete...

Backing Up and Restoring Prime Infrastructure

As with any other system upon which your organization relies, you will need to ensure that Cisco Prime Infrastructure is backed up regularly, so it can be restored in case of hardware or other failure.

Types of Prime Infrastructure Backups

Prime Infrastructure creates two types of backup files:

Application backups: These contain all application code and data, but do not include host-specific settings, such as the server hostname and IP address. You can create these backups using the Prime Infrastructure interface or the command line. By default, Prime Infrastructure creates one application backup every day, automatically, in the default local backup repository. Appliance backups: These contain all application code, data, and host-specific settings, including the hostname, IP address, subnet mask, and default gateway. You can create appliance backups from the command line only. Prime Infrastructure...

A branch is a named pointer to a commit. Selecting a branch in Git terminology is called to checkout a branch. If you are working in a certain branch, the creation of a new commit advances this pointer to the newly created commit.

Each commit knows their parents (predecessors). Successors are retrieved by traversing the commit graph starting from branches or other refs, symbolic references (for example: HEAD) or explicit commit objects. This way a branch defines its own line of descendants in the overall version graph formed by all commits in the repository.

You can create a new branch from an existing one and change the code independently from other branches. One of the branches is the default (typically named _master ). The default branch is the one for which a local branch is automatically created when cloning the repository.


When you commit your changes into a repository this creates a new commit object in the Git repository....

Chrome supports a number of different release channels. We use these channels to slowly roll out updates to users, starting with our close to daily Canary channel builds, all the way up to our Stable channel releases that happen every 6 weeks roughly.


Windows 64-bit

All channels may be run in parallel -- they install into distinct directories and use dedicated User Data directories.

Windows 32-bit

All channels may be run in parallel -- they install into distinct directories and use dedicated User Data directories.




How do I choose which channel to use?

The release channels for chrome range from the most stable and tested (Stable channel) to completely untested and likely least stable (Canary channel). On Windows, Android, and Linux, you can run all channels alongside all others, as they do not share profiles with one another. On Mac, you can run the Canary channel builds...
