Hi, I am still on YunoHost 11.1.21.4 (stable) and with no updates for 11.2 when I check. Is this normal at the moment? Thanks
Nope, let’s check sudo apt policy yunohost to investigate
Thanks, Aleks!
Here’s the output from the command
yunohost:
Installed: 11.1.21.4
Candidate: 11.1.21.4
Version table:
*** 11.1.21.4 100
100 /var/lib/dpkg/status
It looks like somehow you don’t have any apt repositories configured for YunoHost … Let’s look at sudo grep -nr yunohost /etc/apt/sources.list*
It gives me a blank response, as in nothing.
I FTPed into my server and found sources.list and sources.list~ files.
When I open sources.list, this is what the file contains
# deb cdrom:[Debian GNU/Linux 11.5.0 _Bullseye_ - Official amd64 NETINST 20220910-10:38]/ bullseye main

Well for some reason that file disappeared then … I don’t think it magically happened, don’t you remember tweaking it …?
I think I may have a long time ago but I don’t remember. So, is there anything I can do now to fix it?
Yes, use a valid sources.list. You can edit it with command apt edit-sources with root user (or sudo)
here is mine to help you:

Thanks! I tried it out and got this error

Thanks for your help!
I tried to run the cmd and got this error

I also ran gpg --keyserver pgpkeys.mit.edu --recv-key FDBB9F3D83BD9E70 and got the same error message

Can you confirm @Aleks ?
Yes, though it’s quite mysterious that both the apt source entry and the yunohost’s apt key magically disappeared from the server …
It runs the command but still gives me the same error
I remember the only command I ran to update issues in the past was sudo apt-get --allow-releaseinfo-change update. Not sure if this would have deleted the keys.
Your installation doesn’t seem to be standard, so i can’t help you much. Sorry.
No worries, I really appreciate your help 
Just one question, is there a way (or what’s the best way) for me to reinstall Yunohost on the same machine?
Make a backup with yunohost for all configurations and all apps. When you install, restore the backup instead of post-install.
If you use a yunohost domain like .ynh.fr, nohost.me or noho.st, you can set a recovery password. If you backup all configurations, it’s not necessary but it’s safer in case you need it. You can do that with this command:
yunohost domain dyndns set-recovery-password
Thank you! One final question. Would you recommend following the steps in the docs or is there a command I can run on my current machine to reinstall Yunohost?
Yes, you can follow the doc. When the install is finish but before the post-install, you copy your backup in /home/yunohost.backup/archives, and after that you can list it with:
yunohost backup list
You can restore it with (replace name with the archive name given by the previous command):
yunohost backup restore name
