Describe your issue
Hi friends,
Redmine 6.1.0~ynh1 installation upgrade or restoration does not work anymore as of Yunohost 12.1.36 because of some ruby incompatibility.
I did installed Redmine 6.1.0~ynh1 in a prior version of Yunohost before, without any problems.
I’ve created an issue in the redmine_ynh repository, but it looks like nobody stops by there. 
EDIT
I’ve tried setting the default ruby version as 3.4.7, as required by the installation, using the rbenv utility. But no avail. Related restoration log is added as **Restoration-2 log** below. Here are the rbenv and restoration commands I tried:
/home/yunohost.backup/archives# rbenv local
rbenv: no local version configured for this directory
/home/yunohost.backup/archives# rbenv local 3.4.7
/home/yunohost.backup/archives# rbenv local
3.4.7
/home/yunohost.backup/archives# rbenv shell
rbenv: no shell-specific version configured
/home/yunohost.backup/archives# rbenv shell 3.4.7
/home/yunohost.backup/archives# rbenv shell
ü3.4.7
/home/yunohost.backup/archives# yunohost backup list
archives: 20251210-090313
/home/yunohost.backup/archives# yunohost backup restore 20251210-090313
Any ideas?
