On Fedora 33 I configured a folder to be mapped with (the LANG variable at the start can be left out):
$ LANG=en_US.utf8 /opt/Citrix/ICAClient/util/configmgr
File Access – Mapped Drives – [Add]
[Save and Close]
I can read and write the folder in the Citrix environment. After an upgrade to Fedora 34 the mapped folder in the Citrix environment is not writeable anymore. The Windows Explorer says something like “cannot write, not enough permission”. But permissions on local computer and in Citrix environment have not changed. Can you reproduce the problem with your Citrix environment?
I see the same the problem with Ubuntu 21.04. But with Ubuntu 20.10 and 20.04 LTS as operating system on the local computer the folder is writeable in the Citrix environment.
