Moved from VPS Control Panel Comparisons Discussion.  @sagherLEASE open a new support topic instead of gatecrashing an existing discussion with support questions.  For support please submit support request in support forums.

May I also suggest that @sagher looks at the myvestacp.com support forum, as it is dedicated to Debian OS users of the script:

@xdude can advise as he's been trying to install CyberPanel on VPS 9, and has been unsuccessful so far.  

I've been using VestaCP since the day I started with VPS 9 in 2018. It's still working great, but I can't recommend it as the original script has not been updated since January of last year. Why I like VestaCP is because of how light and fast it is.  You need very few specs to run the panel.

@sohamb03 who also has VPS 9 has been using a fork of VestaCP (from Belgium) very successfully but with CentOS 7.  So if you are interested to use his fork of VestaCP, you will have to change to CentOS 7.

If you want to try VestaCP for Debian specifically, there is another VestaCP fork that is fully up to date that has been created for specific use with Debian. You can check it out here:

How to install
Download the installation script:

Code: (Select All)

curl -O http://c.myvestacp.com/vst-install-debian.sh

Then run it:

Code: (Select All)

bash vst-install-debian.sh

Source: https://myvestacp.com/#details

I got following error while installing package. 

Code: (Select All)

The following packages have unmet dependencies:
 exim4-daemon-heavy : Depends: libmariadbclient18 (>= 10.1.44-0+deb9u1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Error: apt-get install failed

@sagher you can manually install the missing dependency "libmariadbclient18" and retry the cyberpanel installation to see if it's working or not. Feel free to post other errors(if encountered any).

@deanhills i am also considered a fair centOS user but but using debian is same as just missing some top of the line packages including but not limited to keyhelp, tinycp, wordops, and many more whenever i need to test out these things i just always spin up a debian VM locally and count me impressed debian devs are as much as awesome as centOS devs. Also if i am not wrong debian is really secure and production friendly with release scedule and self sufficient environment and all, just image if debian was owned by privately held comapny like Redhat for example they would have commercial love(they still do have but not as much as RHEL recieves for support). Debian is a great choice if you are thinking of moving away from centOS.

@TrK  i try many ways to fix it but error at every side. will you please guide me or upload here this file manually?

hmm instesting, @sagher can you check if you are able to download any files in your VM as if the error "no space left on device" is true that means the physical drive(s) are running out of space. Also did you tried it with a fresh installation? if not i will first recommend doing so and if failed feel free to ask dean to assign the issue to me i will gladly take a look on that when i am free.

Bud you have run out of disk space on your disk or the partition where the directory is. Check your disk space usage (use df -h command). It is also possible that even though it may say you have free disk space there is still an issue with storage (possible things: run out of inodes, oversold storage on host node, etc...).

It's a known issue and I'm amazed to see it hasn't been fixed till now; see here:
https://post4vps.com/Thread-Virmach-VPS-...5#pid39685

[deanhills]

If there is a space issue, the correct way to solve the issue is for @sagher to make a request in the VPS Support Forum, which t @sagher has done a couple or more posts ago.

I am Stuck here. how to get out from it with correct configuration ? 

Code: (Select All)

***** PROBLEM: Hostname kvm-Post2Host-LosAngeles.example.com is not pointing to your server (IP address xxx.xxx.xxx.xxx)
Without pointing your hostname to your IP, LetsEncrypt SSL will not be generated for your server hostname.
Try to setup an A record in your DNS, pointing your hostname kvm-Post2Host-LosAngeles.example.com to IP address xxx.xxx.xxx.xxx and then press ENTER.
(or register ns1.kvm-Post2Host-LosAngeles.example.com and ns2.kvm-Post2Host-LosAngeles.example.com as DNS Nameservers and put those Nameservers on kvm-Post2Host-LosAngeles.example.com domain)
If we detect that hostname is still not pointing to your IP, installer will not add LetsEncrypt SSL certificate to your hosting panel (unsigned SSL will be used instead).

[Mashiro]

@sagher

The error / warning message is pretty clear (at least in my humble opinion).

The installer tries to create a Let's Encrypt TLS certificate for your server based on the hostname of your server. The hostname of or your server is however a hostname that doesn't exist as a real domain or if it exists it is not pointed to the IP address of your VPS.

The best way to fix this would be to change the hostname of your VPS to a domain that you own and that is pointed to the IP address of your VPS. Or otherwise accept that a self signed TLS certificate will be used.
