 +GITLAB NOTES: 
 If we have merged in gitlab but there's a bit of a mess in my local repo, we do this. Also recommended as a regular HOUSEKEEPING. Reason is that **git fetch --prune delete the reference to branches that don't exist on the remote anymore. Is really a macro equal to git fetch --all && git remote prune** If we have merged in gitlab but there's a bit of a mess in my local repo, we do this. Also recommended as a regular HOUSEKEEPING.

 +===== UBUNTU 22 - NEW INSTALLS =====
 +** Important **: During installation, select an appropiate uid and gui, not in use in the nfs server. In our case: 1010 and 1010 will work.
 +Example : santosj uid: 1010 ; gui: 1010
 +
 +==== NFS ====
 +For the installation (server and client), follow this link: [[https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nfs-mount-on-ubuntu-20-04|External Link]]
 +
 +In the server Add a new line like this to ''/etc/exports'' repalce the IP with the one for the new client 
 +  /home/pi        192.168.0.11(rw,async,no_root_squash,no_subtree_check)
 +  systemctl restart nfs-server
 +  exportfs -av
 +
 +In the server as well We create the same user as the client (with the same uid). Then we add that user to the ''pi'' group. Finally we change permissions for the folder we want to have write privileges:
 +  useradd -u 1010 santosj    # creates the user with the matching uid. no need to have a home folder 
 +  usermod -a -G pi santosj    # adds ''santosj'' to the server's ''pi'' group  
 +  chmod -R ug+rw /home/pi/Downloads    # This allos group members (''santosj'' among them) to rw in the folder
 +  
 +In the client we create the mounting folder, we add fstab for automount and also can try to mount in manually
 +  sudo cat /etc/fstab
 +  192.168.0.112:/home/pi /home/jaimenfs/nfs nfs defaults,user,noauto,relatime,rw 0 0
 +  #
 +  (santosj)$ mkdir nfs
 +  (santosj)$ mount 192.168.0.112:/home/pi /home/jaimenfs/nfs    # the IP is the one of the nfs server
 +  
 +
 +==== Audio ====
 +If headphones connect but no audio, remove pulseaudio and install new pipewire [[https://linuxconfig.org/how-to-install-pipewire-on-ubuntu-linux|External Link]]
