I tried to install the client with apt-get, but that did not work, so I used snap.
#snap install nextcloud
nextcloud 16.0.5snap3 from Nextcloud✓ installed
No indication of where is was installed or how to start it. I don’t think it was really installed. Only the installer was installed.
I found nextcloud.manual-install in /snap/bin/ so I ran that with the two parameters.
#nextcloud.manual-install myusername mypassword
Nextcloud was successfully installed
I still cannot find a client.
bash: nextcloud: command not found
I am using MATE as my DE, it is not in my menus.
The version number (16.0.5) suggests that you installed the Nextcloud server and not the client. I don’t know if there is a snap of the client but there is an official AppImage and flathub offers a Flatpak.
I tried to follow the install instructions here:
It went well until the end:
#apt install nextcloud-client
