I am running this on Fedora and Ubuntu is not really an option as I have other items hosted on this server.

I did install it via the Snap package. Update though, once the initial upload of files finished it seems that it went back and got the files it missed due to the exception. I restarted the service (which I did try prior to posting) and the errors no longer showed up. Only ignored files show and other files that I know previously had an issue uploading did upload.

Strange that the issue just went away though.

@jaredbusch Not really a solution to the problem.

This was already a fresh installation. I also verified the download as well.

Yes they are

All,

I keep having this issue when uploading files to my newly installed NextCloud instance.

I have tried all of the fixes I could find online and still have no success.

Here is the error that I am getting and it is occurring with a lot of files. Obviously, I have modified the log to remove any personal information (mainly just file names).

7/30/2018 8:22:41 PM, first-part-of-path/e00/d00/e00009c8.au, Nextcloud,Error transferring nextcloud_server/e00/d00/e00009c8.au - server replied: Internal Server Error (An exception occurred while executing 'INSERT INTO oc_file_locks (key,lock,ttl) SELECT ?,?,?

SQLSTATE[40001]: Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction)

I can not figure out for the life of me what is wrong. I have attempted to switch to the other methods of Memcache. I attempted to stop my apache server and clear out the oc_file_lock table among other things that I found to try online.

All still result in having this issue.

Any help is appreciated! it is driving me nuts!

@travisdh1 You are more than welcome to do the write up as I do not think I would have that kind of time at the moment. :(.

Though if you have any questions I can certainly answer them for you.

@travisdh1 step-by-step guide for the entire guacamole installation?

@travisdh1 If you would like I can help you get yours up and running.

As far as getting LDAP to work, I did the following:

Modify /etc/tomcat/tomcat.conf add the following at the end: GUACAMOLE_HOME=/etc/guacamole

If that directory doesn't exist, create it.

Make a file called guacamole.properties. It should contain the following

#Hostname and port of guacamole proxy
guacd-hostname: localhost
guacd-port: 4822

#Location to read extra .jar's from
lib-directory: /etc/guacamole/extension

#Authentication provider class
#auth-provider: net.sourceforge.guacamole.net.basic.BasicFileAuthenticationProvider

#Properties used by BasicFileAuthenticationProvider
#basic-user-mapping: /etc/guacamole/user-mapping.xml

#LDAP Properties
ldap-hostname: ldapserver.name
ldap-port: ldap-port
ldap-encryption-method: ssl (you can delete this line if you are not doing ssl)
ldap-search-bind-dn: self-explanatory
ldap-search-bind-password: self-explanatory
ldap-config-base-dn: self-explanatory
ldap-user-base-dn: self-explanatory

Save the file.

Make a directory called extensions
toss the guacamole-auth-ldap-0.9.14.jar file from the guacamole website there (you can find it here: http://guacamole.apache.org/releases/0.9.14/)

Restart httpd, tomcat, guacd in that order.

as long as your settings were correct this should enable ldap to work without a problem (it did for me).

If you do opt for SSL to be enabled, make sure you have enabled the ssl mod for apache, otherwise it will not work

@black3dynamite Not in my case.. I disabled SE linux to avoid it having issues.

BINGO!

Turns out that even if you have the dependencies installed per the installation instructions on the guac site, if you install from fedora repo you need to install the corresponding libraries also provided by the fedora repo.

these libraries are.. libguac-0.9.14-1.fc28.x86_64 libguac-client-rdp-0.9.14-1.fc28.x86_64 libguac-client-ssh-0.9.14-1.fc28.x86_64 libguac-client-telnet-0.9.14-1.fc28.x86_64 libguac-client-vnc-0.9.14-1.fc28.x86_64 libguac-devel-0.9.14-1.fc28.x86_64

This is assuming 64 bit and the latest 0.9.14-1 guacd was installed.

All is working for me now except fonts which i know i havent installed yet so that should be an easy fix.

Terminus fonts seems to work very well as it comes with the standard monospace font.

terminus-fonts is the package if anyone is interested.

@travisdh1 sounds good. I am working on it now myself so if i find something beforehand i will definitely share it!

Alright... good news and bad news... I have everything working. The authentication issue was caused by my SSL certificate not being properly installed. fixed that and i can log in and everything works great... except..... I get Connected to Guacamole. waiting for a response and it times out.

So I guess I have the client up and running but the daemon is not working properly.

So far the guacd seems to work. I have the login page, however my LDAP authentication has yet to work which is how we authenticate log ins and create connections. I'll update once i can log in to let everyone know if this works.

@scottalanmiller As it turns out this issue has already been resolved by the Guacamole Dev team, however instead of releasing it for 0.9.4 they are fixing it in the upcoming 1.0.0 release.

They do not have a date, however, after reading through a few forums, it seems that most of the bugs for the 1.0.0 release are fixed and they are just updating documentation at this point. Perhaps we will see version 1.0.0 in the near future.

So in short... no one has an answer to the topic that's sad news. I will keep trying to see if i can get GCC 6 installed on Fedora 28 and post my results if i succeed.

Any luck on this?

I need to build Guacamole on Fedora 28 but i am getting the same error. Someone on the apache e-mail list said they forced compiled guacamole using CC6 but i am unsure on how to do that and i assume i would have to have it installed first as well. From my understanding its a simple as adding CC="gccX" ./configure and so on but i have not been able to install CC6.
