At PHZ the standard Linux distribution and version provided by PHZ IT Support is Ubuntu 22.04 LTS. Our policy is (by experience) to wait roughly one year after the LTS version is initially released, to avoid the early bugs and the time and effort to fix them. After a year the most common issues are typicaly resolved and the LTS is ready for wider spread adoption. However, courageous developers, who don’t mind, and IT support also on one prototype machine can start experimenting with the early versions to find out how mature the release is.
Overall, our IT Support has been happy with 22.04 LTS and it has had smoother experience than many of the previous versions. However, here is a list of common issues and standing problems, with potential fixes.
Files don’t work over FUSE mounts
This is very annoying new feature, causing apps to crash, when you try to upload a file over a network mount. We have had Samba mounts for more than 20 years, but now with Ubuntu 22.04 LTS they are rendered very hard to use. If you are not careful, you might loose hours of work when the email or documents that you have been carefully writing.
Crashing
* Thunderbird
* Libre Office
Workarounds
- save often. Use Save as Draft on Thunderbird.
- copy the file to local disk (e.g. Downloads). Then select it from the local disk instead of network drive
Drives list disappears
After long uptime, at some point the drive -list disappears from some file upload menus such as Documents, Downloads.
Workaround
It seems that this is a rendering issue, you can still click the ”invisible” drives/folders, so it’s just an annoyance.
File Browser file path not editable
On some UIs there is an ”improvement” so that you can’t anymore directly write the path to a file by keyboard, but you need to click it through. This very slow and annoying ”UX improvement”.
OpenVPN weak MD5 Signature
After OpenVPN security upgrade, the MD5 signatures are deprecated.
Workaround
While we are upgrading the serverside MD5 signatures, you can add the following line to your openvpn config.
tls-cipher "DEFAULT:@SECLEVEL=0"
